Midfielder Mohamed Diame has joined Hull City on a three-year deal.
Samuel Eto'o has rejected rumours which suggest is ready to quit Chelsea, claiming he is wholeheartedly committed to the club.
The Cameroon striker has scored seven times in 27 appearances since signing a one-year contract in August 2013.
However, recent reports have claimed the former Barcelona and Inter Milan forward is prepared to leave the London club rather than push on towards a new contract.

"False and degrading information has been published about me," the 32-year-old posted on Instagram.
"I just want to remind to all that I have a tremendous love for Chelsea. I have a lot of respect for my leaders and teammates.
"I love Chelsea fans and I will keep on giving everything I have to defend the Blues."
