DONS boss Derek McInnes believes it will take brave hearts and calm heads for them to beat Real Sociedad at Pittodrie tonight.
McInnes admitted there is a temptation to throw caution to the wind and go all out from the start for those goals.
But he knows the La Liga side are capable of killing the tie if they do anything rash.
McInnes said: “We will need to be brave going forward, but not reckless.
“I doubt if their approach will be too different to what it was in the first leg.
“They don’t need to score, they know the onus is on us to get at them.”
