The Vitaliy Mykolenko-Jake O’Brien partnership is about as conservative a pair as can be found in the Premier League. O’Brien led all Premier League full-backs for aerial duels won last season, perhaps little surprise given the 6ft 6in Irishman has been stationed in the auxiliary role for some time. Given there are 20 teams in the Premier League and two regular full-backs per side, it’s an indication of his shortcomings. The name that jumped off the page as above the median for both metrics was Krepin Diatta. ​Last season, Diatta won 79% of his defensive duels in Ligue 1 and, despite being 5ft 9in, ranked second for aerial duels won.
