Chelsea manager Jose Mourinho insists Manchester United have had all the luck this season and bemoaned their good fortune in grabbing a late winner at Fulham.
Cristiano Ronaldo's last-gasp goal at Craven Cottage helped to extend United's lead over Chelsea in the Premiership to nine points, although Mourinho's side do have a game in hand.
United have also been fortunate with injuries this term, while Mourinho has had to contend with John Terry, Petr Cech and Ashley Cole being sidelined at important times.
"This is a season in which United have had no injuries and every player is fine to play," said Mourinho.
"They go to the Champions League and have a disallowed goal for the opponent (Lille) and their goal is that goal.
"They go to Fulham and it looks like they deserve to lose and they win. They play at Tottenham, it's 0-0 and Ronaldo dives, they get a penalty and win 4-0. It looks like everything is on their side, but that's football.
"I didn't see the Fulham game to be fair, but the information I have is it was completely undeserved. It's a game they could have lost and in the end they win it.
"In the Premiership all we can do is keep winning and see if the next step is to close the gap or to open the gap.
"If the next step is to close the gap and we can go from six points to four points, then everything is open."
