Celta Vigo legend Alexander Mostovoi has sparked controversy suggesting "briefcases" will be involved for his old team's clash with Real Madrid.

Barcelona need Celta to beat Real tonight to keep their title hopes alive.

And Mostovoi told Okdiario: "I see a difficult game for Celta, Real Madrid are playing for the league, they are in good form, they play well and they score a lot, while Celta have been losing a lot of games in the league and they are in a negative dynamic.

"They could've won against Manchester United. I think they are not in shape to complicate the life of Real Madrid.

"I think there may be briefcases, and why not? Barcelona is also playing for the league, and they can give bonuses to win. In eight years that I was there we always played for something in the last days, whether for entering the Champions League or Europa League.

"Sometimes I said that it was better to stay in the back positions where you can make money..."
