Saha believes Mbappe will prove the difference in the Champions League showdown.
“Paris Saint-Germain are slightly ahead because they kept progressing," he told Omnisport when asked to compare the teams. “They have a player like Mbappe who cannot be stopped."
“Man United are a great club with quality players. Paris Saint-Germain are solid because the head coach brought more stability between defence and attack. The coach can easily switch his system, he's very clever and has great communication. He has great coaching staff able to identify the opponent's philosophy. We saw him changing his system several times during a game.
“The team has evolved a lot. They haven't taken it to the next level in the Champions League, those few steps left to reach the final. They lacked those elements: the right information, atmosphere, balance, reaction to what cannot be predicted. The coach needs to deal with it, giving the right space and confidence to the players while keeping his defence ready. It's a balance to reach that is different in Champions League to the league."
