Arsenal goalkeeper Petr Cech made a surprise appearance at Wimbledon on Saturday ahead of the tournament's opening.

The 34-year-old is close friends with Radek Stepanek and joined his compatriot on the practice court at SW19.

Cech stood at the back of the court and even acted as a ball boy for Stepanek ahead of his first-round clash with Nick Kyrgios.

Stepanek is a wild card for the tournament and opens his All England Club campaign against the Australian on Tuesday.

Cech also met Austrian world No. 8 Dominic Thiem, who is a big Chelsea fan, on Saturday.

He has returned to England following Czech Republic's early exit from Euro 2016.

The Czech's finished fourth in Group D with just one point, coming in the 2-2 draw with Croatia.

Andy Murray was also put through his paces on Saturday as he prepares for his clash with fellow Brit Liam Broady.

He could face the winner of Stepanek vs Kyrgios in the fourth-round, should they reach that stage.

Murray has avoided facing Roger Federer, who beat him in last year's semi-final, before the final as the Swiss superstar is on the other side of the draw.
