The future of Kepa Arrizabalaga as Chelsea's number one goalkeeper continues to be a hot topic ahead of the summer transfer window.
The Spaniard lost his place in goal earlier this year, with Frank Lampard instead preferring Willy Caballero for some vital games in the Premier League, FA Cup and Champions League.
And although Kepa came back into the side earlier this month - and put in two impressive performances in wins against Liverpool and Everton - there remain doubts over whether Lampard sees him as the long-term number one.
Chelsea may well look to sign another goalkeeper in the summer, with Ajax's Andre Onana, Udinese's Juan Musso and Barcelona's Marc Andre ter Stegen among the players they have been linked with.
But former Barcelona star Rivaldo has urged his old side to tie the German goalkeeper down to a new contract in a bid to ward off interest from Chelsea, or any other potential suitors.
"Barcelona are negotiating a contract renewal with the goalkeeper Ter Stegen, and I agree that he deserves an improved salary for all he has been doing for the club in the last few years," Rivaldo told Betfair.
"Of course, much will depend on the player's demands as I don't believe either that he should earn a similar salary to [Luis] Suárez or [Lionel] Messi, but he should become one of the better paid members of the squad.
"He transmits safety and a team is built from the back.
"He knows how to play with his feet, has already saved the team many times and he's clearly deserving of a better income."
