Manchester City striker Carlos Tevez has apologised for his recent conduct following his touchline row with manager Roberto Mancini in September.
The 28-year-old returned to the club last week , following a self-imposed, three-month exile in Argentina.
"I wish to apologise sincerely and unreservedly to everybody I have let down and to whom my actions have caused offence," Tevez said in a statement.
He has also withdrawn his appeal against the club's misconduct charge.
"My wish is to concentrate on playing football for Manchester City Football Club," he added.
The Argentina international has been missing from the City squad since November and has not featured for the club after boss Roberto Mancini alleged the striker refused to come on as a substitute during City's 2-0 defeat by Bayern Munich in a Champions League tie in September, although Tevez claimed there had been a misunderstanding.
Straight after the incident, Mancini claimed the Argentine was "finished" at City, though he later suggested an apology would put an end to the matter.
Tevez was suspended and later fined for misconduct before he flew back to South America to begin his unauthorised leave on 7 November, for which he has lost nearly £10m in salary, fines and bonuses payments.
During his three-month absence, the former Manchester United and West Ham striker was linked with transfer window moves to AC Milan, Inter Milan and Paris Saint-Germain but failed to secure a switch away from Manchester. West Ham chairman David Gold has also revealed his club made a number of attempts to bring the player back to Upton Park on loan.
Earlier this month relations seemed to have thawed and Mancini named the Argentine in his 25-man squad for the remainder of the season.
BBC Sport understands that neither the striker or Mancini have spoken to each other since the striker arrived back at Manchester City last Tuesday.
The forward has since begun a training program designed to return him to fitness. He is not in the club's European squad ahead of their Europa League clash against Porto as he is not registered for the competition.
