Manchester United's defensive worries continue to mount following their 1-0 derby defeat to rivals City, with Marco Rojo stretchered off with a dislocated shoulder.

Chris Smalling was sent off during the first half and Rojo's injury 11 minutes into the second period leaves Louis van Gaal with mounting injury concerns ahead of next week's home clash with Crystal Palace.

Van Gaal confirmed after the game Rojo had dislocated his shoulder - an injury so bad television didn't show the replay.

Rojo, the £16million Argentine defender, stayed down after sliding into a challenge during the second-half on compatriot Martin Demichelis.

The former Sporting Lisbon man received treatment for four minutes before departing the scene at the Etihad Stadium, having to be stretchered off after receiving oxygen from medics.

With Phil Jones and Jonny Evans both injured, Van Gaal ended with a centre-back pairing of Michael Carrick and Paddy McNair as Sergio Aguero separated the two sides.
