Former Manchester United striker Terry Gibson has warned his old club not to underestimate Granada.

United and Granada meet on Thursday in the first-leg of their Europa League quarterfinal.

“United can't afford to take them lightly," Gibson told United's club media. “They're going to play like an away team at home. They'll look to play on the counter-attack, which they're good at.

“They're a fluent team who change tactics a lot but they won't be as naïve as Real Sociedad were; they won't open up and allow themselves to be hit on the counter-attack. They'll look to keep it nice and tight and hope to be in the tie for the second leg.

“It's a dream tie for Granada, it's clearly the biggest game in the history of the club. This is their second season back in La Liga. They were kind of like a Sheffield United last season in that they were a massive surprise."
