Scotland boss Gordon Strachan has told Leigh Griffiths not to over-celebrate if he scores what could potentially be the goal that secures their World Cup play-off spot on Sunday.

Scotland face Slovenia on Sunday night knowing that a win would be enough to take them into the play-off positions.

As per the Sunday Post, the Celtic striker is giving his international manager a headache over his discipline record.

A number of players are one yellow card away from missing the next World Cup qualifier and Strachan knows the importance of the player’s keeping their heads.

Griffiths has been known to be booked for his celebrations in the past. Strachan says Scotland cannot afford to lose Griffiths for the remaining games.
