He's often spotted looking glum and moody on and off the tennis court.

But it turns out BBC Sports Personality of the Year winner Andy Murray does have a sense of humour as seen in some Christmas photos posted online with his brother Jamie.

The brothers, who were part of the victorious British Davis Cup team, were pictured wearing novelty Christmas jumpers on their mother Judy's Twitter account.

Arsenal fan Andy, 28, a former Wimbledon and US Open champion, was also pictured wearing a club shirt with Alexis Sanchez's name on the back while Jamie dons a Manchester United shirt.

Although the brothers have rarely faced each other on the tennis court, with older brother Jamie, 29, and partner John Peers beating Andy and Leander Paes in the Rogers Cup this year in their first senior meeting, they clearly take their football rivalry a lot more seriously.

The younger Murray had more reason to smile than Jamie thanks to Arsenal's 3-0 win over the Red Devils earlier this season, with the Gunners currently sitting second in the Barclays Premier League table. 

The brothers don't have much rivalry on the court, but on the football pitch it is clearly a different story

Andy won the BBC sports gong in a ceremony last weekend for the second time in three years.

He was integral to Britain's success in the Davis Cup, winning both his singles matches against Belgians David Goffin and Ruben Bemelmans and teaming up with Jamie to defeat Goffin and Steve Darcis, as Team GB triumphed 3-1.

It was the first time Britain has won the Davis Cup since 1936.
