5) Virgil van Dijk (Southampton and Liverpool)
We could have easily put Jaap Stam on this list. After all, the Dutchman did win the famous treble during his first season at Manchester United but van Dijk’s impact on his team, in general, was more significant.
Liverpool would not have managed to win the Champions League and the Premier League in successive seasons without him. You also have to factor in that he won the PFA Player of the Year and came close to winning Ballon d’Or; no mean feat for a centre-half.
