Robbie Keane opened the scoring after we'd dictated possession in the first half. City controversially levelled when Stephen Ireland prodded home from an offside position just before the hour and then Nedum Onuoha headed home the winner after 72 minutes. Darren Bent's late 'goal' was chalked off late on as another offside decision went against us.
"It was extremely important for us, we had had three games with no goals and three games with one point," said Eriksson.
"I don't think we played badly in the first half but we should have been more lively and shown less respect.
"I think we did it in the second half and scored two goals. I think if you look at the game we deserved to win it."
Eriksson said it was time his side had some good luck. "I don't remember when the linesman helped us the last time - it has been many times for the opposition," said the Swede.
"I don't know if he did this time but I think we deserved to win, we created more chances than they did."
City boss Sven Goran Eriksson insisted his side deserved their 2-1 success on Sunday.
