[OC] With new strikers arriving, who should stay? João Pedro looks untouchable, but what about Nicolas Jackson and Liam Delap? I compared them with public available data. Will Guiu be sold and Emegha will take his spot?

I was bored and did not know how to kill some time, so here we go lol

I am a little bit worried about the striker/forward depth. We currently have Liam Delap, Nicolas Jackson, Emmanuel Emegha, Marc Guiu and João Pedro.

I used FBref style match logs and Python/Jupyter Notebook to analyse the data. There are missing metrics, especially around injuries and availability. FBref has become horrible since the beginning of the year, so I had to take data from other sources such as FotMob and so on.

Maybe it is not a completely fair comparison, as Delap had injury interruptions:

Season Injury From Until Days Games missed
25/26 Ill 13/01/2026 16/01/2026 4 days 1
25/26 Shoulder injury 06/12/2025 25/12/2025 20 days 4
25/26 Hamstring injury 31/08/2025 28/10/2025 59 days 10

But I was curious and compared our strikers for the next season anyway.

Metric João Pedro Liam Delap Nicolas Jackson
Minutes 3969 1680 1323
Goals 23 2 11
Assists 6 3 3
G+A 29 5 14
Goals/90 0.522 0.107 0.748
Assists/90 0.136 0.161 0.204
G+A/90 0.658 0.268 0.952
Shots/90 2.358 2.839 3.810
SoT/90 0.930 0.911 2.177
Conversion % 22.1% 3.8% 19.6%
Minutes per G+A 136.9 336.0 94.5

The big point: Jackson produces actual end product.

Delap takes shots and has more total minutes, but the output is not close. But I think we all know this lol.

So the backup does not only need to be a big body. The squad needs someone who can do at least one of these two things:

A) replace João Pedro’s output when he rests
\B) offer a different tactical profile without killing the attack

And that is where Jackson beats Delap.

Why Delap’s case is difficult

The issue with Delap is end product. He offers rotation value and gets shots off, but the final output is not close enough to João Pedro or Jackson.

Area Evidence Interpretation
Goalscoring output 0.107 goals/90 Very low for a João Pedro backup.
Overall output 0.268 G+A/90 Too far below João Pedro’s 0.658 and Jackson’s 0.952.
Finishing 3.8% conversion The biggest red flag in his profile.
Efficiency 840 minutes per goal Extremely weak compared with Jackson’s 120.3 minutes per goal.
Bench impact 0.173 G+A/90 as substitute Despite many sub appearances, the impact is limited.
Starter alternative 0.310 G+A/90 as starter Not convincing enough as a João Pedro replacement in the XI.
Discipline 2.143 fouls/90, 0.482 cards/90 More combative, but also more likely to give away fouls/cards.

The caveats with Nicolas Jackson:

Area Evidence Interpretation
Smaller sample / not enough data 1323 minutes Less secure sample than João Pedro and Delap.
Lower fouls won 0.891 fouls won/90 Does not replicate João Pedro’s ability to win fouls.
Higher offsides 0.980 offsides/90 More likely to mistime runs or play on the shoulder aggressively.
Discipline risk 0.624 cards/90 Highest cards rate in the comparison.
Availability/context Bundesliga break / AFCON period His monthly trend needs context and should not be read as a simple form drop.

Why João Pedro needs a reliable backup:

Area Evidence Interpretation
Heavy workload 3969 minutes The squad needs rotation cover.
Starter dependency 45 starts Too many starts increase the risk of fatigue or injuries.
Need for rest 67.3 minutes per appearance A backup needs to protect his minutes.

That is a big gap compared with João Pedro and Jackson

Metric Delap Jackson
Goals/90 0.107 0.748
G+A/90 0.268 0.952
Conversion 3.8% 19.6%
Minutes per goal 840.0 120.3

To keep this simple, I used João Pedro as the benchmark. Keep in mind he played nearly 4000 minutes, which is around three times more than Jackson. The question is not who is the better player overall, but who profiles better as his backup for rotation, rest and attacking output.

Player Goals/90 Assists/90 G+A/90
João Pedro 0.522 0.136 0.658
Liam Delap 0.107 0.161 0.268
Nicolas Jackson 0.748 0.204 0.952

Now we come to the shooting and threat data:

Player Shots SoT Shots/90 SoT/90 Shot Accuracy % Conversion %
João Pedro 104 41 2.358 0.930 39.4% 22.1%
Liam Delap 53 17 2.839 0.911 32.1% 3.8%
Nicolas Jackson 56 32 3.810 2.177 57.1% 19.6%

Who is more dangerous from the bench?

We also lack on players, who are brining in an impact from the bench...

Player Sub Minutes Sub Goals Sub G+A Sub G+A/90
João Pedro 375 2 4 0.960
Liam Delap 519 1 1 0.173
Nicolas Jackson 236 4 4 1.525

https://preview.redd.it/g9b5uoembd2h1.png?width=2836&format=png&auto=webp&s=97a5ea8526d89402558059fd9a5cda803cca492c

The monthly trend is useful, but it needs context. Jackson’s line is more volatile because his minutes are not spread as evenly across the period. There is also an interruption around the Bundesliga winter break and AFCON/international availability period, so the empty or low months should not automatically be treated as poor form.

https://preview.redd.it/br8nhcxrbd2h1.png?width=2836&format=png&auto=webp&s=ff412560c9158798c8f78e9eb2084889e9295663

What matters more is what happens when he actually gets minutes: his productive months are much stronger than Delap’s. Delap has one clear spike, but otherwise his monthly G+A per 90 is mostly flat or close to zero. Jackson’s form line is less stable, but the upside is much higher.

Next, the efficiency chart:

Delap’s main issue is output cost. His minutes per goal and minutes per goal contribution are far higher than João Pedro and Jackson. Jackson is much closer to João Pedro’s efficiency profile.

https://preview.redd.it/bsoie0rnbd2h1.png?width=2836&format=png&auto=webp&s=5ff03dcc97c69f26cca0952a9caca6f379ee858d

Small note: this chart mixes percentage metrics and time-based metrics. For shot accuracy and conversion, higher is better. For minutes per goal and minutes per goal contribution, lower is better.

Jackson gives you Why it matters
More goal threat Better chance of replacing João Pedro’s scoring output
More shots on target More direct danger for the opposition goalkeeper
Better conversion Much closer to João Pedro’s finishing level
Better starter output More convincing if João Pedro needs rest from the XI
Better bench output More useful as an impact option
Better recent form Stronger current attacking trend
Closer attacking replacement Better fit if the squad needs output cover

But will be Jackson ready to be a backup or rotation player? What about him as a left winger, as we also lack on the left side...

Overall, I would pick Nicolas Jackson as the better sporting backup to João Pedro.

Delap’s best argument is workload. He has more minutes, more appearances and a more physical rotation profile. But if the backup role is about protecting João Pedro’s output when he rests, Jackson is clearly stronger.

If you have any suggestions or see any errors, please let me know : )
