Louis van Gaal has rejected suggestions that Manchester United must bolster their defence in the January transfer window.

Van Gaal claimed United have "more than enough" defensive cover and quality, despite Chris Smalling's groin problem further stretching resources after he was forced off in the first half of the 2-1 win against Southampton.

Robin van Persie's brace secured victory at St Mary's on Monday, but the Red Devils still struggled defensively.

And despite having to switch midfielder Michael Carrick into a makeshift defensive role midway through the game, Van Gaal was adamant that his squad does not need improving.
