Arsenal manager Arsene Wenger has confirmed that Hector Bellerin will be on the sidelines for the next four weeks after suffering an ankle injury.
The 21-year-old sparked concern over his fitness after he withdrew from the Spain Under-21s squad last Wednesday during the international break.
Bellerin was a doubt heading into this Saturday's Premier League showdown against Manchester United, and not only will he miss the trip to Old Trafford, the full-back will be absent for the next four weeks.
In Thursday's press conference, Wenger told reporters that Bellerin suffered the injury as a result of a "very strong tackle" from Danny Rose in the "last 10 seconds" of the Gunners' 1-1 draw with North London rivals Tottenham Hotspur on November 6.
The right-back is likely to miss league games against Bournemouth, West Ham United, Stoke City and Everton, as well as Champions League group matches against Paris Saint-Germain and Basel.
