Arsenal striker Danny Welbeck is still in hospital with the ankle injury he suffered against Sporting CP in the Europa League on Thursday.
Welbeck was carried off on a stretcher in the 30th minute at the Emirates Stadium, having landed awkwardly on his ankle after going up for a header.
He received oxygen as his leg was strapped with a protective brace with up to ten medical staff in attendance. He was replaced by Pierre-Emerick Aubameyang and sent straight to hospital.
Sky Sports News reports that the injury is now being described as 'significant', with a further update expected in the next 72 hours.
