Manchester United fullback Rafael is battling to make their crunch game with Arsenal.
The Daily Mail says Rafael is facing a race to be fit for Manchester United's clash with Arsenal on Sunday after damaging his ankle ligaments.
The Brazilian right-back came off during United's 3-1 win at Fulham on Saturday and did not take part in an open training session at Carrington today, ahead of the trip to Real Sociedad in the Champions League.
He will not be involved in San Sebastian and will remain in Manchester for treatment.
