Tevez fights to meet match demands

LONDON, England -- Argentine striker Carlos Tevez admits he has a stamina problem as Manchester United target a Champions League, Premier League and FA Cup win treble.

The 23-year-old Tevez is United's second-highest scorer this season with 13 goals in all competitions, but the player feels he has still not reached his best.

"I am playing at a 70 or 80 percent of what I can really do," he told Radio Del Plata.

"I'm finding it quite difficult to get over each match. In the last 25 minutes, the level drops. I always do my best but it's difficult for me to keep this level."

The Argentina international feels so fatigued that he is looking at the possibility of not joining up with his national team for the World Cup qualifier against Brazil in June.

He said: "My body needs a rest. I have had no holidays for two years. I want to be calm, with my family, thinking about nothing for 20 days.

"Since the Copa America (last summer), I've had no rest. I will see how I am in May, when the season finishes."

Tevez left domestic football in Argentina in December 2004 when he joined Brazilian giants Corinthinians, but says he plans to return before retiring and win another title with Boca.

He moved to the Premier League initially with West Ham in controversial style before switching to Old Trafford last summer.

"I would like to play four or five more years in Europe. I would love this to happen at Manchester United and then go back to Argentina.

"I know I will finish my career at Boca. No doubt about it. I do not imagine myself retiring without winning one more title there."

In the meantime Tevez is happy at Old Trafford and has nothing but praise for his team-mates as they continue to challenge on three fronts.

"(Wayne) Rooney is a a phenomenon and a great man. (Paul) Scholes is unbelievable. I see him every day. His quality and personality are tremendous. He is the engine of this team," he said. E-mail to a friend
