Europa League: Aberdeen v Real Sociedad team news

Aberdeen manager Derek McInnes will have virtually a full squad to choose from for the second leg of the Europa League third qualifying round clash with Real Sociedad at Pittodrie on Thursday evening.

Defender Clark Robertson is set to be the only absentee for the Dons as he is not yet fully match fit despite playing for an hour in a friendly on Tuesday.

The League Cup winners trail the La Liga giants 2-0 following the first leg in Spain after David Zurutuza and Sergio Canales gave the Basques a comfortable win.

McInnes knows his side will have to produce an improved performance if they are to turn the tie around – and he expects Sociedad will make them fight all the way.

He told RedTV: "Here's hoping they take their foot off the gas, but I wouldn't imagine so. We can't bank on it.

"All we can do is put a bit of doubt in their heads by the way we play.

"I would assume they will come here in a professional manner. They were really up for the game over there and I wouldn't expect anything different from them.

"If we are to get a result it will be a result of what we do and not what the opposition does."

A sell-out 20,000 crowd will roar the Dons on at Pittodrie and McInnes admits his side must score first to have any chance.

"A 2-0 scoreline over there was not a disgrace but we still feel we can do better," he said.

"It's half-time in the tie and they have a big advantage. But 2-0 in any game is still a result you are never totally comfortable with if you are winning at half-time.

"The next goal is always important in a 90-minute game. This will be no different.

"So it's important that the first goal is an Aberdeen goal. If they score it makes it a massive job for us. But if we can get it, hopefully the momentum change can help us.

"There is still a lot to play for and we are not giving up. We still feel that playing at home with a huge crowd behind us, we can get a positive result that takes us through the tie."
