I think I want that Rafa book! 
Watched some of the Davis Cup - Jack Draper played really well but just didn’t do enough in the tiebreaks - had a few double faults
I wasn’t going to watch the Djok match as I thought it would be an annihilation but it doesn’t seem to be going all his way - he is about to go 5-3 in the first set against Norris though!
GB might not need the doubles - the GB bucket hats are very popular though - somebody must be making a profit
