3. Eric Dier
Stats- 29 appearances
Brought in from Tottenham Hotspurs as an emergency winter signing, Eric Dier went on to prove many people wrong as he played a crucial part in Bayern's second half of the season. The English defender filled in for the frequently injured center-backs and performed immensely in the big UCL games against Arsenal and Real Madrid — and just for that one can say that the transfer was worth it.
This season, however, Dier hasn’t been getting a lot of playing time since he’s not considered to be suited for Kompany’s high-line system. Hence he is likely to leave the club next summer but for a modest fee of €4m the signing turned out to be alright.
