McGrath wrote in the Sunday World: "Chelsea are in with a real shout of the Premier League title this season. I just have a feeling that Jose Mourinho could be about to strike gold in his first season back in charge at Stamford Bridge.
"I know that he returned as a boss willing to do the bidding of owner Roman Abramovich, and thus set up Chelsea in a much more attacking mode than was the case in his first term. But I loved what Jose did at Arsenal last Monday night, when he sent out a team set up not to lose.
"It was a real pro's performance from a great coach and an old pro like me would have revelled in it even if I wasn't a Chelsea fan since boyhood. Chelsea were compact, forcing a team that likes to go wide and use its pace on to the inside.
"Their older warriors also came through in a big game and worked really hard on a wild night when there were a few players, on both sides, who didn't want to know. I thought men such as John Terry, Frank Lampard and John Obi Mikel were real leaders for the Blues, standing up and fighting for what they wanted, which was at least a point."
