Argentine FA president Julio Grondona has speculated that Carlos Tevez has been left out of the Argentina side to face Portugal because he opted out of last year's clasico against Brazil.

20303 - Tevez's 'attitude' to blame for Argentina omission

Tevez pulled out of the squad in November claiming to be injured, but netted twice for Manchester City against Fulham in the Premier League just four days later. Now, while coach Sergio Batista has kept quiet on the subject, Grondona has seen fit to make his views on the subject clear.

"I think that Tevez's absence is because of his attitude when he didn't come to play [against Brazil] and shortly after he took the field for his club," Grondona told Radio Pop. "That attitude didn't go down well with the coaching staff, it was a lot easier to tell us that he didn't want to come."

Grondona also hit back at rumours that Tevez had been dropped from the side because of his close relationship with former boss Diego Maradona.

"Tevez's absence has nothing to do with Maradona, we cannot go down that road,'' he added. ''I want to leave that crystal clear."
