Manchester United attacker Anthony Martial was unhappy losing his No9 shirt last season to Zlatan Ibrahimovic.
Martial was forced to give up the jersey to the Swede, despite scoring 17 goals during a fruitful first year at the club following his arrival from Monaco.
The Manchester Evening News reports the France international was unhappy with the Red Devils' decision to move him to No11 instead.
An Old Trafford source told them that Martial's 'head was in the clouds' following his shirt number swap.
However, Martial has regrouped this season and is producing career best form for United and manager Jose Mourinho.
