Manchester United boss Ole Gunnar Solskjaer has hit out at Barcelona midfielder Sergi Busquets.

Solskjaer has claimed Busquets shouldn't be playing in the Nou Camp on Wednesday after escaping a red card at Old Trafford.

And he's hoping the officials in the second leg of their Champions League quarterfinal in Spain will be stronger dealing with Barcelona's “tricks".

“I don't want to bang on about being unlucky with some decisions, but Barcelona should have had a player sent off after about 15 minutes.

“Busquets should not be playing in the second game because he got away with such a lot.

“We can't do anything about it, but it's important that the officials realise that Barcelona don't just play good football. They are a streetwise side.

“They were constantly cajoling the referee, speaking to him, making him their friend.

“That's something our players must look at because they will play in a lot of these games in the years to come.

“Barcelona are clever. They're experienced. They've got all the tricks.

“And the longer you play this game, the more you learn those tricks and you know what's required."
