ABERDEEN boss Derek McInnes believes his side will be 'big underdogs' for their Battle of Britain Europa League clash with Burnley.

The Clarets' return to Europe after 51 years away has seen them paired with the Dons for a Europa League second qualifying round tie.

The first leg will take place at Pittodrie on Thursday, July 26, with the return at Turf Moor a week later.

McInnes steered Aberdeen to second in the Scottish Premiership last season but he insists Sean Dyche's side will be heavy favourites to progress to the third qualifying round.

"It's a fantastic draw. We'll be playing against a team that has done exceptionally well in what is regarded as the best league in the world," the Dons boss said.

"It should be a fabulous contest. They are favourites in every tie and they're seeded for a good reason.

"We know we'll be big underdogs for this one, but rest assured we'll be doing all we possibly can to cause an upset.

"There will be a terrific atmosphere at Pittodrie and I wouldn't be surprised if it's a sell out."
