The discrepancy in his strong crosses-stopped numbers and what is seen when watching him at corners is made clearer knowing he conceded eight goals from 85 corners faced last season, according to Opta.

Conceding 9% of all corners faced, when compared to all Premier League keepers who faced more than 20 corners last season, places 15 keepers as having a better percentage and 12 as having worse.

Interestingly, Aston Villa’s Martinez ranked second best, only conceding two goals from corners having faced 60. Lammens’ 9%, however, is a big improvement on United’s first-choice keeper last season, Andre Onana, who conceded 17.2%.

It is key to note these numbers are influenced by the quality of the league, opposition faced, and the defending team’s ability to defend corners. United’s team-wide defending of corners has been questionable at times and the Premier League’s physicality, inventive corner routines and use of individuals to apply physical contact on keepers, may cause Lammens’ numbers to become slightly worse as he learns to adapt to the league.

His confidence, aggression and height do give him useful raw tools to improve in these situations if coached around when to come and how to position himself.
