Frank Lampard hopes Chelsea team-mate John Terry can follow him by signing a new contract with the club.
Argentina striker Sergio Aguero insists he is happy at Manchester City.
Arjen Robben's father is adamant the Holland international will not leave Bayern Munich this summer.
Rumours have been circulating regarding the former Chelsea winger's future after suggestions his Bayern team-mates are unhappy with his ego.
France and Bayern star Franck Ribery recently implied he was not a close friend with Robben, which fuelled rumours of the latter's unpopularity.
But Robben is under contract until the summer of 2015, having only signed a new deal in May.
And his father, Hans Robben, told Sport-Bild weekly: "Arjen is under contract with Bayern Munich. Arjen leaving Bayern is ruled out.
"He will play for Bayern Munich next season, no matter what."
