Kris Commons today told John Guidetti that he needs to be as streetwise off the park as he is on it.

The Hoops forward was yesterday censured by the SFA after being found guilty of making a "comment of an offensive nature".

Guidetti, on-loan from Manchester City this season, was filmed on Dutch television singing what was alleged to be an offensive song about Rangers.

While Commons insisted that it was a matter strictly between the player and the club, he has urged Guidetti to be wary of the potential for trouble away from football.

"It isn't something that we would speak about in the dressing room," said Commons. "It was between John and the club because we have more important things to concentrate on.

"Things that happen off the field go over our head.

"When you play for Celtic or any other high profile club you have to be very wary of what you do off the park. That is not anything new.

"When you sign for a high profile club you have to be wary of what you say, what you tweet, what you text, what you do in press conferences because there is a backlash if you do anything wrong but that is just part and parcel of being a professional footballer.

Meanwhile, Commons has welcomed the idea of re-introducing a permanent winter break into Scottish football - but he doesn't believe that it would benefit clubs trying to negotiate summer qualifiers to make it into the group stages of the UEFA Champions League.

Arguably Celtic's biggest games of the season come in July when they face the qualifying games and it is the lack of competitive games at that point which Commons believes is the hindrance.

"It is something that we have to deal with," he said. "A winter break would be nice when the weather is at its worst and pitches are at their worst. But I don't think that is going to have any sort of effect on qualifiers in July. It is not going to help us out in that aspect but the break, especially when you have players who are away on international duty and travelling all over the world, will help us come back and play at a high standard.

"I sometimes feel sorry for the likes of Efe Ambrose and Emilio Izaguirre who sometimes have to travel halfway around the world for a friendly and then come back and have to try and perform at a high level. "

And Commons has also revealed that there are no plans in the Celtic dressing room for a party on Saturday afternoon should they beat Dundee tonight and Dundee United beat Aberdeen tomorrow - a scenario that would make the Hoops champions.

"We've not even spoken about it, not even mentioned it once in the last couple of days training, about anything happening on Saturday night," he said.
