Chelsea will try to sign a goalkeeper this summer because Frank Lampard is not convinced Kepa Arrizabalaga has a future as his long-term No 1 at Stamford Bridge.
Several clubs in Spain have expressed an interest in signing Arrizabalaga but Chelsea want to get back as much of the world-record £71m they paid for him two years ago as possible.

Chelsea are looking at a list of goalkeepers including Jan Oblak, Andre Onana and Nick Pope.
Atletico Madrid have said that Oblak is not for sale so Chelsea would have to pay his £110m release clause to get him.
Onana would be the cheaper option. He wants to move to the Premier League and Ajax will listen to offers.
Pope established himself as one of the best goalkeepers in the Premier League this season, keeping 15 clean sheets at Burnley.
Lampard is expected to start Willy Caballero in goal for Saturday's FA Cup final against Arsenal, after he replaced Arrizabalaga for the crucial final game of the season with Wolves.
Caballero has started all of Chelsea's FA Cup games this season except the 2-0 win against Liverpool in March.
Chelsea conceded 54 goals in the Premier League this season, more than any other side in the top half of the table.
They also remain in the hunt for highly-rated Bayer Leverkusen midfielder Kai Havertz, who is keen to move to Chelsea after scoring 12 goals in 30 Bundesliga appearances this season.
Leverkusen value Havertz at £90m but all parties are hopeful a £70m deal, plus add-ons, can be done.
Brazilian winger Willian is expected to renew his contract at Chelsea this week despite interest from several other Premier League clubs, including Arsenal and Manchester United.
There are question marks over the futures of several other Chelsea players including Jorginho, Emerson, Marcos Alonso, Davide Zappacosta, Michy Batshuayi and Tiemoue Bakayoko.
Carra: Chelsea will go no further unless they change goalkeeper
Sky Sports pundit Jamie Carragher believes Chelsea require an upgrade in the goalkeeping department if they are to achieve their ambitions.
During the 5-3 defeat to Liverpool, Carragher said: "Chelsea will go no further unless they change the goalkeeper.
"I know they keep buying a lot of attackers but you see how many goals they have conceded. I think a lot of that is down to the goalkeeper, if I am being totally honest.
"It is an area that - if they want to compete with Liverpool and Manchester City - they will have to rectify in the summer."
Bosnich: It is quite evident Kepa will be on his way
Former Chelsea goalkeeper Mark Bosnich believes Arrizabalaga's days at Stamford Bridge are numbered.
"He hasn't had a particularly good season and the bottom line is you have a fall-out with the manager in any kind of way it's a slippery slope," Bosnich told Sky Sports News.
"So I can fully understand Frank wanting to basically take that level up and to say look listen he's just not for me, I want somebody else.
"If that's the case then there's going to be an issue as the club shelled out so much money for him. I don't think they'll be able to recoup that money, they may be able to recoup some.
"And of course the goalkeeper can make it very difficult for Chelsea by saying that if you are going to sit me out of the team then I'll stay here on these massive wages and run down my contract for nothing.
"They've got a big decision to make. I think it's quite evident from what we've seen, and the fact that he didn't play in that last game of the season, that he will be on his way."
The summer transfer window will run for 10 weeks from July 27 and close at 11pm on October 5. A domestic-only window for trades between the Premier League and EFL then runs from October 5 and closes on Friday October 16 at 5pm.
