The Gers ended pre-season with a 3-1 defeat at Ibrox.
Rangers manager Mark Warburton
The scoreline finished 3-1 to the Premier League new boys and despite showing flashes of quality, Rangers struggled to cope with their visitors.

“We have got to look at what we normally do well,” said Warburton. “Today, we gave the ball away cheaply on occasions, dropped too deep on occasions and didn’t press together.
“But, at the same time, we will take lots of positives out the game as well.
“We played with the ball well at times, didn’t penetrate enough which I appreciate, but we have to look at the game and recognise who we are playing against, and step up,” he added.

Burnley took the lead after just three minutes when Andre Gray converted from 12 yards after being upended by Clint Hill inside the area.
The pacey forward grabbed his second of the game 15 minutes later after latching on to an excellent Scott Arfield pass and finishing comprehensively past Wes Foderingham.
Gray completed his hat-trick in fine fashion in the 54th minute when he collected a Lukas Jutkiewicz knockdown and fired past Matt Gilks from just outside the area.

Rangers pulled one back in the final stages when a ricochet in the box caused the ball to deflect in off Ben Mee after a driven Michael O’Halloran cross.
Today’s game marked the Gers’ first real test of pre-season, with their participation in the new League Cup group stage limiting their ability to play against tougher opposition.
Warburton will have learned a great deal about several of his squad and will be fully aware of the improvements that need to made if they are to halt Celtic’s title charge this season.
