Chelsea boss Jose Mourinho says Romelu Lukaku's attitude was the reason he let the striker move to Everton.
The Wigan Athletic reunion at Everton continues apace with goalkeeper Joel Robles becoming the third former Latics player to move to Goodison Park this summer.
Robles, who spent last season on loan at the DW Stadium from Atletico Madrid, has signed a five-year deal and follows Antolin Alcaraz and Arouna Kone to the club as new manager Roberto Martinez continues to recruit his former players in the North West.
Kone arrived on a three-year deal for an undisclosed fee while Alcarez was signed on a free transfer.
A statement on Atletico's website read: "Atletico Madrid and Everton have reached an agreement for the transfer of Joel Robles to the English club.
"The goalkeeper, who ended last season playing on loan at Wigan, will compete in the Premier League following the agreement reached between the three parties. In our club we wish him luck in this new stage of his career."
Everton also released a statement, which read: "Everton have completed the signing of talented goalkeeper Joel Robles.
"The 23-year-old glovesman arrives at Goodison Park from Atletico Madrid on a five-year deal for an undisclosed fee."
