French number one Jo-Wilfried Tsonga has admitted that he shouldn't have played in the Davis Cup final.
The 29-year-old has been forced to pull out of this month's Australian Open after failing to recover from a forearm problem.
"I should never have played the Davis Cup final," Tsonga told Europe 1.
"Knowing all that, obviously I should never have played the final, like I should never have played Bercy (November), like I should have not played at all from the month of September to have time to recover from this injury and be fighting fit for the the 2015 season.
"It's a part of my career which has been quite complicated and which has left its mark. For the moment, I still haven't recovered from that. I think I'll reflect on that a little later in the season."
Tsonga reached the final of the Australian Open in 2008, but on that occasion he was beaten by Novak Djokovic.
