Celtic manager Ronny Deila has warned his players that they will be given a stern test by Partick Thistle on Wednesday night.

The Scottish Premiership leaders can take a step closer to retaining their title tomorrow when they welcome the Jags to Parkhead.

Partick head into the match on the back of three wins from their last four games, and Deila believes that they will provide his side with tough opposition.

"This game is important and Partick Thistle are one of the best teams just now – they've had a good spell with some good results so it will be a good test for us," he told CelticTV.

"We're getting closer all the time but when you get closer, the games become bigger and tomorrow night's game against Partick Thistle is a very big game for us. If we win, it puts more pressure on Aberdeen, but if we lose, it's open again."

Celtic are currently seven points ahead of second-placed Aberdeen in the table.
