Manchester United boss Erik ten Hag has lost Anthony Martial for Sunday's clash with Arsenal.
After kicking off his reign with losses to Brighton and Brentford, the Dutch manager followed the key victory against rivals Liverpool with a pair of a dogged 1-0 wins on the road.
Martial missed the opening two games of the season with a hamstring complaint and returned as a half-time substitute against Jurgen Klopp's Reds, providing the assist for Marcus Rashford's decisive goal.
But an Achilles complaint ruled the France international out of the away triumphs at Southampton and Leicester, with the forward laid low again when table-topping Arsenal come to Old Trafford on Saturday.
"Anthony Martial will not be involved for Sunday," Ten Hag said. "I cannot tell in this moment (when he will be available again)."
