Captain delighted after difficult derby win
The midfielder marked his return from injury with a penalty strike that sealed the victory and Arsenal's place at the top of the table with ten minutes remaining.
"At times it was very difficult," Fabregas told ESPN. "It has been over the past few years against West Ham.
"It's a London derby and everyone always wants to win, it's always tough to play."
Adding further difficulty for Arsenal was the controversial sending off of Thomas Vermaelen, who brought down Guillermo Franco prior to the break.
The match officials left the pitch to a chorus of boos at half time as it appeared that the veteran Mexican striker made a meal off minimal contact from the Arsenal defender.
Asked whether he agreed that the challenge warranted a sending off and a penalty, Fabregas said: "I had no clear view of the incident, it was 50/50. The referee said it was 100%, he will know better."
The Spaniard, whose 18th goal of the season secured victory, insisted that his side could go on to win the league despite the squad suffering from a series of long-term injuries to key figures such as Robin van Persie and Aaron Ramsey.
"We want to go all the way with the squad we have, we want to prove that," he said.
