20 most overpriced signings of this summer transfer window

#6 John Stones (Everton to Manchester City)

The one thing Pep Guardiola desperately wanted at Manchester City was a ball-playing defender and his wish was granted when Manchester City paid an incredible 58.5 million Euro to sign John Stones. Stones has had an impressive start to the Guardiola era and he will have to continue performing at a high level if he is to justify the huge price tag.

Everton	Manchester City	38.2	58.5	20.3

#5 Granit Xhaka (Borussia Monchengladbach to Arsenal)

Granit Xhaka always put in consistent performances for Borussia Monchengladbach in midfield, but Arsene Wenger surprised quite a few people when he paid over the odds to sign the Swiss midfielder. Wenger will be hoping that Xhaka adds some much-needed steel to the Arsenal midfield.
