Modern football's common metric for judging chance quality, Expected Goals (xG), uses data to determine how likely a player is to convert a chance.

But who have been the most wasteful players across Europe's top-five leagues this season? We've looked at the biggest underperformers between xG and goals scored.

David Brooks leads thePremier League for xG underperformance this season, with the Bournemouth winger managing just one goal from an Expected Goals figure of 5.65.

Brooks should take some shooting tips from Wales teammate Harry Wilson, who tops thePremier League for over-performance (+4.7).

Issa Soumare certainly makes his presence felt for Le Havre. The Senegalese forward ranks in the top five players inLigue 1 for shots taken, fouls committed and fouls won. His six goals have helped Le Havre pull away from the relegation places, though it's a total that could - and should - be higher.

RB Leipzig spent around €20m to sign Romulo last summer, with the Brazilian fresh from a 17-goal season with Göztepe in Turkey.

The 24-year-old's had a decent season, scoring eight times and providing four assists in theBundesliga. A little fine-tuning around goal could help Romulo become the ideal heir to Benjamin Sesko and Lois Openda's goals.

A flurry of goals late last season persuaded Union Berlin to make Andrej Ilic's loan move permanent, but the Serbian striker's failed to deliver in 2025-26.

Ilic has underperformed his xG by a massive -7.05, which includes a missed penalty against Hamburg in September. He's scored just twice in the Bundesliga all season.

Everything appeared to come together forMoise Kean last season. The Fiorentina forward scored 25 goals in all competitions in what appeared to be a coming-of-age campaign.

He was named in theSerie A Team of the Year as a result, but the ex-Everton man has failed to replicate that level this time around. He's scored a respectable eight goals in Serie A
