Gibson completed a move to Goodison Park on Friday after failing to hold down a regular slot in the United side over the last couple of seasons, and Saha believes that his current club should raid the Red Devils once more.
"After Darren can we have Diouf and Pogba too?!? Just askin. Would be great too. Just sayin," Saha posted on Twitter.
Saha, 33, left United to join Everton in 2008.
