Celtic manager Brendan Rodgers claims a ‘fit and intense’ Leigh Griffiths can only be a good thing for his side.
Griffiths scored the only goal to put Celtic into the Scottish League Cup semi-final on Wednesday, where the Hoops saw off St Johnstone to go on to face Hearts.

The 28-year old Scotland international has scored five goals in 14 appearances this season, and his performance earlier this week earner praise from his manager.
As reported by Sky Sports, Rodgers said this of the former Wolves striker:
Leigh did what he does best, in and around the box, if you look at his three goals – all predatory in their own different ways.
So to get three goals in three games [is great], and he will tell you himself, he could have had a hat-trick [in the league cup match], but he is always there.
That is why he has the goal record that he has. He has an incredible goals to games ratio that he has here at Celtic.
And if he can keep up that level of fitness and keep up that intensity, that work and movement, everything else follow and it really benefits the team.
