Former Chelsea striker Chris Sutton believes the club must resolve their goalkeeper situation before next season.
The Blues are strengthening several areas of the team ahead of the coming campaign.
And Sutton believes Kepa Arrizabalaga should be replaced by a top keeper so they can compete for trophies under Frank Lampard.
He told Stadium Astro: "What's been the positives for Chelsea this season?
"The likes of [Mason] Mount coming to the fore, Tammy Abraham coming to the fore, they've now done some good business with Ziyech and Werner, so things are looking up.
"But they need to do some more business as well.
"I think the goalkeeper is a massive issue and defensively they've conceded too many goals.
"Frank will know that but there's no point worrying about that at this moment in time.
"Get over the line, get a Champions League spot, you know the riches which come from the Champions League and the finance which comes with that, and then he can address all these issues once the season finishes."
