Manchester United defender Chris Smalling admits they were disappointed with defeat to Europa League opponents Ajax.

Smalling says, the Reds will study footage of the match to ensure similar mistakes aren't made in the future.

"We're through to the next round," he told MUTV. "That's what we can take from it, but it was a very disappointing game.

"When we came off the pitch we felt like we'd lost the tie. But at the end of the day we've made it through and we now have to make up for it in the next round.

"I've not seen too much of [Athletic Bilbao} but La Liga's a strong league. It's going to be another tricky tie.

"We'll have to look at the video [from tonight] and hopefully we'll play better at the weekend [against Norwich]."
