Aberdeen manager Derek McInnes wants his players to give Real Sociedad as uncomfortable a game as possible at Pittodrie tonight.
The Dons trail the Spaniards 2-0 following the first leg of their third qualifying round Europa League tie at Anoeta Stadium in San Sebastian last week.
Sociedad are in the driving seat to make the play-off round but McInnes has not given up hope of completing a spectacular comeback.
He said: “We have to get on the ball, we have to help each other in possession of the ball, ask more questions of them defensively and make sure they don’t enjoy it.
“If they come here and start to enjoy the game then good players will be allowed to be good players.
“For us to get the maximum from the game and give us our best chance of winning the game, we have to get after them and make things more uncomfortable for them than it was in San Sebastian.”
Despite the 2-0 loss in Spain McInnes believes his side can take positives going into tonight’s game at a sold-out Pittodrie.
He said: “We started the game fine and we worked around their shape. We looked quite comfortable.
“But then they stole possession from us a couple of times and whether it spooked us, I am not so sure.
“They finished the first half stronger and started the second half stronger but we finished the last 15 minutes our fitness levels kicked in and we looked stronger.
“We started well and we finished well but we will need to have more of the ball certainly in their half.”
