Roger Federer and Stan Wawrinka appeared to have put any recent differences behind them after the world number two posted a picture on Twitter of the Davis Cup team-mates looking all smiles.

Reports emerged on Monday that the pair had an argument following their semi-final at the ATP World Tour Finals last week, with the suggestion that Federer's wife Mirka may have heckled Wawrinka during the last-four encounter.

The Daily Mail reported Federer and Wawrinka were involved in a "furious row" behind the scenes.

That would have been a concern for Swiss Davis Cup captain Severin Luthi who leads the team into the final against France on Friday, but the star pair have now put on a show of unity.

"It's great being with the boys again," Tweeted Federer, above a picture including himself and Wawrinka with arms around each other. In the shot, world number four Wawrinka makes playful 'bunny ears' behind his team-mate's head.

Of more concern now for the Swiss will be Federer's fitness after the 17-time grand slam winner was forced to withdraw from Sunday's London final against Novak Djokovic due to a back injury.
