'I’m . not going to lie, it’s going to be really difficult but when I get . inside the ropes I’m going to have to try and concentrate on the matter . in hand. 'Obviously . (it's) quite a difficult time for Caroline and myself. It was mutual . and amicable and we both thought it was the best for us, the best for . both of us.'

Speaking to reporters at the halfway stage, he said: 'Golf is the number one priority to me . and while I'm on this run of form I want to try and keep it going as . long as possible.
