Celtic boss Brendan Rodgers admits his side will need to be patient when they take on Rosenborg in the second leg of their Champions League qualifier.

The pair meet on Wednesday in Trondheim fora spot in the play-off round and chance to earn their place in lucrative group stages of Europe’s biggest club competition.

A sluggish display from the Bhoys led to a 0-0 draw in last week’s opening game at Parkhead but having outclassed Sunderland in a friendly on Saturday, they appear to be getting sharper with every outing.

Rodgers admits his team were off the pace at times in the opening leg and were made to work hard by a team who are already halfway through their own domestic campaign.

He believes patience will be the key at the Lerkendal Stadion and has urged his players to bide their time.

“They’re a team who are used to dominating the ball and we pushed them back,” he said.

“Of course we’re not at the same level of fitness as them but we still showed a lot of good moments and created some half-chances.

“This part of the season, we won’t be at our fluent best, like last season, but we’re a lot better than what we were in terms of our game idea.

We won’t be where we were three quarters of the way through last season but naturally we’re trying to find our fitness and qualify.”

Celtic are 2.60 to win in Trondheim, with another draw priced at 3.20. The hosts are available at 2.75.
