Rémi is perfect for physical work, and it's very important for arnaud, it's his strong point.
But, yes, if he could have someone with him during the matches, as in davis cup, it would be perfect !!!
some years ago, they wanted to do new rules.. and tried in some tournaments, where coaches were autorised to coach their player during a match...I think it's a rule made for Arnaud !!!! LOL
Please, Guy, coach arnaud !!!!!!
