Marcus Rashford says Manchester United wouldn't have beaten Astana two years ago.

United beat the resilient Kazakh side 1-0 at Old Trafford on Thursday night in their opening game of the Europa League.

"It wasn't the best performance but there was a lot of good stuff, they're tough to break down," Rashford told reporters.

"If I look back to two years ago, I don't think the team had the togetherness to come through a game like that.

"Everyone expects it to be easy but the opposition have come to win so it's always tough."
