The Scot presented the Barca striker with the Golden Shoe at an awards ceremony on Wednesday evening in recognition of the Uruguayan's 31-goal exploits for the Reds last season.
Speaking at the event, Dalglish backed Suarez for success at Camp Nou, and jokingly said that Liverpool could take the Uruguay international back if his switch fails to work out.
He said: "I don't think there is anyone who can stop him. He was brilliant at Ajax and Liverpool and I'm sure he will be success.
"And if it doesn't work out he can always come back to Liverpool on loan!"
Dalglish managed Suarez for 18 months at Anfield before he was replaced at the helm by Brendan Rodgers in the summer of 2012.
