Tottenham were leading 1-0 through Sandro's first goal for the club when assistant Mike Cairns wrongly ruled Heurelho Gomes had spilt Frank Lampard's shot over his own line.
That was compounded in the 89th minute when colleague Martin Yerby failed to spot Salomon Kalou was offside when netting the winning goal.
The Italian admitted his side had been fortunate, saying: "We were lucky. We have to be honest to say this because looking at the [goals] on the television, we can say the decision was wrong but it was a very difficult decision.
"We have to accept this when things are good for us and also when things are against us."
