It's an odd situation, this tennis. Players are nose to nose in the locker room and the practise courts and presumably you've got to be more or less civil, pax Connors, and then you've got to go on court, forget all the chumminess and whop them! Thought the pics of Andy and Delboy practising on the same court
just before their match, quite bizarre.
Don't suppose it happens in boxing....or that many other sports. Imagine footballers sharing the same dressing room
