The keeper recently announced that he will not ink a new deal as he wants to move on, but the club remain hopeful that the 31-year-old will have a change of heart
The 31-year-old stopper recently stated that he will not be extending his contract with the Catalan giants, which is due to expire in 2014, but the Barca supremo remains hopeful that a change of heart could be on the cards.
"He said he wanted to quit Barca, but I still hope he will change his mind. We'll always keep the door open for him in case he changes his mind," Rosell told reporters.
"The Camp Nou showed how much they love Valdes during the 5-1 win over Osasuna.
"There's still time and we haven't started looking for a replacement yet. The Camp Nou often gives its judgement for the better or the worse and the people always show what they think and what they want."
The Catalans' president then went on to state that they have never received any offers for star player Lionel Messi, who will sign a contract extension until 2018 next week.
"We've never received any offers for him, but there's nothing unusual about that. It just means that everyone knows how committed he is to Barca. The club have never heard of any attempt and if it has, I'm sure it was stopped in its tracks early."
The 25-year-old will become the third player in a week to commit their future to the Blaugrana following the recent contract renewals of Carles Puyol and Xavi.
