Kepa Arrizabalaga has been dropped by Chelsea in favor of Willy Caballero but Frank Lampard insists he still has a future with the club.
Chelsea also bought Edouard Mendy from Rennes for approximately £20 million.
Kepa has been ridiculed for a series of high-profile mistakes.
"I certainly won't go to the point of [saying] he's played his last game for Chelsea," said Lampard.
"I think it has been a difficult time for Kepa. That's been well documented. I know it, he knows it, but we certainly shouldn't jump to that conclusion.
"Also, [something] which I felt quite strongly about in the last week, is to understand that Kepa is a young man and an awful lot of the highlight or spotlight on him has become slightly unfair.
"I have to protect him because I know he is a good lad and playing with absolute professionalism and intent to do the best he can, as all the squad have done. That's all I want to say about him now."
