Paul Annacone: 'Roger Federer's environment is complex'

has a lot of off-court commitments. The Swiss player gives several interviews to reporters coming from all over the world during each tournament, his press conferences always last many minutes and he has 11 endorsements, which means having photo shoots and advertisements videos and attending the off-court events they hold.

The week prior to a Grand Slam, for any top player but especially for Federer, is always very busy from this point of view. , who was Federers coach from 2010 to 2013, spoke about how Roger manages to give his best in tennis although he has a very busy life.

I worked with for eight years as well, and he did not have to do as many things as Roger, admitted Annacone speaking to TW USA. Roger has even more things to do but he understands how important time is, and he does an incredible job in managing his time so that he prioritizes tennis.

For the coach, its about understanding the person you are working with and what his environment is. His environment is very complex but he handles it very well. Annacone, who is currently a Tennis Channel commentator, also reflected on some of the toughest losses he had while coaching Roger: 2010 US Open and 2011 US Open, when in both matches Federer did not convert two match points each.

That was very difficult, its always tough to lose and especially when you get so close to getting to the final, admitted Annacone. Its emotionally challenging and I know that it is even more difficult for the player.

But when I took a step back and I looked at the great matches, I noticed that maybe he should have not won some ones and so I put that in perspective. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
