CELTIC manager Brendan Rodgers has revealed that striker Leigh Griffiths is struggling with an injury problem ahead of Wednesday's Champions League qualifier against Linfield.

The Scotland international is a doubt for the second leg clash at Celtic Park after picking up a calf problem, but Rodgers insists the niggle is not a major concern.

Griffiths started in the 2-0 first leg win in Belfast last Friday, but was charged by UEFA on Monday for provoking the home fans at the end of the game when he tied a scarf to one of the goalposts.

Speaking ahead of the match, Rodgers said: “(Griffiths) might be struggling for fitness. He has a calf injury but it’s nothing serious, we’ll see how he is tomorrow.”

The Bhoys will face either Dundalk or Rosenborg in the next round should they progress and Rodgers hopes his side can show their more clinical side in the first competitive home match of the season.

He said: “We'll expect another tough game in terms of having to break down a really low defensive block.

“You have to give credit to the Linfield boys. When they sat in they made it very difficult.

“We had 27 shots and 13 on target. Tomorrow night we hope to be more clinical.”

The Northern Irishman also fielded questions about two players with uncertain futures, Emilio Izaguirre and Kolo Toure.

He revealed that Honduras international Izaguirre could be leaving the club and European football altogether in the near future.

“He's come back in and been training,” said Rodgers.

“There's maybe an opportunity for him to go elsewhere outside of Europe. It's something we'll speak with him and his agent about and then we’ll take it from there.”

Former Liverpool defender Toure joined the Hoops last summer on a one-year contract, but Rodgers suggested the Ivorian could still have a future at Parkhead in an off-pitch role.

"His contract is up but there will always be a door open here for him for a different role if that’s what he sees."
