Victor Moyes was left unimpressed with the referees at the London stadium but fells his vying crew have enhanced and he was pleased with their performances.
The 53 year old Black Cats manager David Moyes demand that disgraced his side to their another league defeat of this season at West Ham should have been stave off out for offside.
The 28 year old new zealand professional footballer Winston Reid fired a shot towards a overloaded box into the bottom right corner in the dying moments of the game to secure their side to victory over the hosts by 1-0.
But the Sunderland coach thinks the away side gas players interfering with players with play, and specially Jonathan Calleri, who was in front of the goalkeeper Jordan Puckford, and that the goal should have not be conceded.
"It was offside," he said in remarks reported by the BBC. "It should be given offside. The referee thinks it is onside. You can tell by the referee's movement to the linesman that he is not sure, they weren't sure but it was not a goal."
In the first half the French international Dimitri Payet hits on the post for the home side, they apropos rallied and should have score the goal after the first half when Wahbi Khazri fired a weak shot at the home goalkeeper Adrian.
"I thought the players played well," said Moyes. "Not in the opening 20 minutes, they bossed us, but we got through it and had good chances. I am very pleased with the performance but not the result.
"I thought we did good things. I did not enjoy the first part, but the second half we were not threatened and if anything we looked more likely to score.
"You have to take your chances. I said in the last few weeks there have been signs of improvement, I thought the players showed it today."
Sunderland will play their next match against Southampton on Wednesday and their next match against Arsenal.
