Rafael Nadal OUT of ATP World Tour finals? Hint that star won’t take on Roger Federer Nadal, 31, withdrew from the Paris Masters just hours before his quarter-final clash with Filip Krajinovic today. The Spaniard called a press conference and said: I was here to win, Im sorry for the fans and organisation. That is the same of Roland Garros, its like family to me. Nadal then gave a clue as to his mindset – fearing playing on could result in his career ending early. And with the season-ending ATP World Tour finals starting at the O2 in just 10 days time, theres little chance for Nadal to fully recover from the ongoing problem. He added: Im not thinking about London, Im thinking long term, to be able to continue playing tennis.. The 16-time Grand Slam champion has already sealed the world No 1 position and playing on could lead to even more issues in 2018. The reward of doing so would be ranking points and prize money – although the former isnt so important this year given top spot has already been secured. Nadal had strapping under his right knee yesterday during the three-set win over Pablo Cuevas. Asked about it after the match, he initially claimed he was 100 per cent and dismissed talk of it keeping him out of London. Anything can happen in one week and a half, Nadal said. But if nothing strange happens then Im going to be there.. But despite his insistence otherwise, Nadal is NOT 100 per cent. The issue is a serious one and although hes never won the season-ending finals, the risk could far exceed any reward. A Nadal withdrawal in London will see as the huge favourite to lift the ATP World Tour finals for a seventh time. Sky Sports expert Mark Petchey cant see Nadal playing in London after todays latest blow. He said: I think hell be very, very doubtful for London, to be honest. If I was betting, Id bet he wouldnt play right now..
