Es-Chelsea goalkeeper Mark Bosnich has warned his former club over selling Kepa Arrizabalaga this summer.
Bosnich believes Kepa, who signed for Chelsea in 2018 should be given more time at the Stamford Bridge to improve. Since completing his £71m world-record move from Atletico, the Spaniard has endured a difficult time in London and was dropped by Frank Lampard in the favor of 38-year-old Willy Caballero.
"I just think it was down to his form which in terms of the standard when he first came, it hasn't been up to scratch this season," he said.
"Frank was well within his rights to leave him out when he did but I thought he did well when he came back.
"I rate Kepa, I thought he was a superb shot-stopper with good agility and his kicking was okay for me. I think people make too much of his problems with distribution but the first job is to keep the ball out of the net. Kicking is a bonus.
"In terms of dominating his box, he is young and slight so it has taken time to get to grips with that. That's something they need to work on. For me, he has not been a disaster in any sense of the word. He has done okay so far."
The 25-year-old signed a seven-year contract with the Blues that is set to expire in the summer of 2025.
