I wonder if Federer hired Lundgren again, if it would help him get back to the top. Lundgren (who is coaching Dimitrov) helped Fed develop his volleying skills and really helped him focus mentally, enough to get him to #1. Does he have the solution for Fed against the top players? Right now, he's helping Dimitrov climb the rankings and certainly Dimitrov performed well against Nadal (the backhand held up well). I wonder if Lundgren would have similar advice for Roger...he has worked with some of the greatest talents in the sport and somehow convinced them to adopt a solid work ethic (Safin, Rios). What do you think?
