After suffering a 5-0 mauling at Highbury last night, Gray said in the YEP: "There's not much you can pick out of it because they were far superior to us and you can't do much about that. It's a disappointing time for something like that to happen, but they were superior to us and I've got no complaints.
"I was disappointed with how we conceded so many goals, but they looked as if they could score at will. They were too much for us. You always think you can do more, but that's easier said than done. They're great technically, they're at the top and playing with bags of confidence.
"They'll make it difficult for most sides and that's why they are top of the league. It just shows the difference between the clubs. Chelsea are paying £100m to try and catch up with them.
"We'll carry on going," he added. "I've got to impress on the players that they won't come up against a team like that again. We've got to get together again and look forward. The lads are disappointed, but they cannot dwell on the game.
"There's four more matches still to play and they're vital to us."
