Manchester United were held to a 2-2 draw by Ange Postecoglou’s side at Old Trafford having led on two occasions.
Rashford scored his fourth Premier League goal of the season deep into the first half and appeared to send a message to his critics, suggesting they talk too much.
Keane has called on Rashford to keep producing as he insisted the forward should not be upset at anybody.
‘We need to see more, he’s showed it before, he’s got the quality. Why does he seem to be upset with everybody, he’s got to go and enjoy it he’s playing for Man United,’ the former midfielder said speaking on Sky Sports.
