Manchester United have received yet another injury blow in the form of Daley Blind, who is expected to be out of action for four to six weeks after suffering a medial ligament injury.

The defender was injured after Latvian forward Eduards Visnakovs landed on his knee in a coming together, and Manager Guus Hiddink believes the player may have done more damage than is visible to the eye.

The extent of the damage is still unknown but he will most certainly miss their game against Arsenal at the Emirates stadium next weekend, along with nine other players, leaving Louis van Gaal searching for inspiration.

Dutch TV believes it is a small tear in his ligament and the player will be available by the New Year, but Hiddink is not taking any chances and will give an official declaration when the player has a full MRI scan.

"I'm am not a doctor, but I'm rather negative. His medial ligament is twisted and there might be a rupture as well. There will be a full MRI scan tomorrow," Hiddink said yesterday.

The likes of Phil Jones (shin splints), Marcos Rojo (dislocated shoulder), Rafael Da Silva (muscle problems), Chris Smalling (thigh) and Jonny Evans (ankle) are all out injured while Michael Carrick withdrew from the England squad citing a groin problem. Ander Herrera has also been on the sidelines for much of the opening half of the season, owing to a fractured rib.

Blind was used as a centre-half in United's 1-0 win over Crystal Palace last weekend, but his unavailability will force van Gaal to fall back on Paddy McNair and Tyler Blackett, who made their debut for United this season.

The Red Devils are currently seventh in the League, 13 points off Chelsea in top spot and need to step up their game if they have to keep their hopes of making it to the top four, alive.
