Manchester United striker Robin van Persie is reportedly unsure about continuing his stay in Old Trafford and is likely to consider his future in the club during the summer with two years still left to his contract post July.
Van Persie was reportedly disgruntled with teammates following United's 2-0 loss to Olympiakos and said that they were occupying positions which he wanted to have.
According to The Guardian, although Van Persie was careful to defend manager David Moyes, his frustration with his fellow players was an implied criticism of the manager's tactical approach as the Dutchman was starved of chances in their opening last-16 first-leg defeat by the Greek champions.
Van Persie was also reportedly disappointed by United's former manager Sir Alex Ferguson, who retired at the end of last year, as Ferguson was a key factor in Van Persie agreeing to sign for United from Arsenal instead of Manchester City in 2012 in a 24-million pounds transfer, despite City having offered him a higher salary.
