Andy Murray admits it will be "difficult" for him to compete for Great Britain in their Davis Cup tie against Serbia in July. The 28-year-old Grand Slam winner led Britain to their first Davis Cup triumph for 79 years in 2015, but is not sure if he will take to the clay court in Belgrade.

The much-anticipated tie is scheduled to take place just five days after the Wimbledon final and Murray admits that could prove to be problematic. "The plan is to play but it is going to be difficult," Murray told BBC Sport. "I need to play it a little bit by ear, as well, because I just don't know how the body is going to respond."

Murray's possible participation in the tie, which could also feature world number one Novak Djokovic, is further complicated by his ambition of playing in the Olympic Games in Rio de Janeiro this summer. The Briton is the current Olympic singles champion and is determined to defend his title later this year.

Looking ahead to the French Open and Wimbledon, Murray said: "These next couple of months are going to be extremely difficult. Changing surfaces – almost on a weekly basis – does increase the chance of injury significantly: not many players would go from playing a grass court tournament one week straight onto the clay the following week with only a couple of days preparation time.

"So I need to make sure my body is good and healthy through the summer because it's going to be a long summer with the Olympics, many long flights, change of surfaces, different continents and different conditions – so I just now need to respect how my body feels as well."
