Sir Alex Ferguson has hinted there may be a mental explanation for the latest setback in injury-ravaged career of Owen Hargreaves.
Handed a surprise start in Saturday's 2-1 win over Wolverhampton Wanderers at Old Trafford, the 29-year-old lasted just six minutes before signalling he could not continue.
Hargreaves was clearly troubled by his left hamstring and made his way dejectedly down the tunnel for treatment.
"It is possibly because of a lack of match fitness," Ferguson told Key103 radio station yesterday. "Maybe a bit of anxiety at playing his first game had a bit to do with it too."
