London, Apr. 9 : Serbian defender Nemanja Vidic has said that Manchester United is guilty of complacency and warned his team mates that they must rediscover their focus if their season is not to end in failure.
In less than four weeks United have seen a seven-point lead at the top of the Premier League cut to just one and face a battle to reach the Champions League semi-finals after a 2-2 draw with Porto at Old Trafford.
