Pallister told William Hill: "Barcelona is a great football club, they are a top team for any player. They have had financial problems, so they may find it difficult to sign Rashford in the summer. But it will also depend on whether Aston Villa decide to buy him permanently.
"He was a £100m player a few years ago, so his valuation has dropped a lot. But there is a player in there, and if he can return to that form, he can go back to being worth that amount."
