Celta Vigo striker John Guidetti slammed Manchester United's tactics for last week's Europa League first-leg semifinal.

United won 1-0 in Vigo, though their time-wasting and defensive play left Guidetti unimpressed.

The former Manchester City forward told La Voz de Galicia: "They didn't play football.

"After their goal they wasted a bunch of time, they did not play football. They are very cunning in that way."

But Guidetti feels Celta will have a better chance at Old Trafford.

He added: "They will have to play more, because their supporters will urge them on and we will have more space."
