Roy Keane tore into Manchester United forward Marcus Rashford for 'smiling too much' ahead of Manchester United's clash with Chelsea at Old Trafford this evening.
Rashford has been the subject of criticism from Keane throughout this season, with the former United captain branding Rashford's performance against Arsenal as being 'like a child'.
"I'm really frustrated with him," said Keane, who is working as a pundit for Sky Sports this evening.
