Yannick Bolasie (Crystal Palace to Everton) – £30m:
The fan favorite at Selhurst Park, Yannick Bolasie made a record move to Everton as he became the costliest outgoing transfer for Crystal Palace. He made 134 appearance for the Eagles but managed just the 12 goals making him an inconsistent player in the Premier League.
According to the CIES Football Observatory values the Congo international at around the £10m mark making him the second most overpriced transfer in the Premier League this summer.
