Arshavin: First goal the turning point
Having squandered leads against both AZ Alkmaar and West Ham United in recent weeks, the Emirates Stadium faithful were still on edge at half-time of the North London derby, despite goals from Robin van Persie and Cesc Fabregas giving the hosts a 2-0 advantage.
However, Van Persie's second on the hour mark settled the nerves, with Arsene Wenger's side going on to seal a convincing 3-0 success against a team level on points with them before kick-off.
And Russian international Arshavin revealed his delight at the team's collective performance.
"We had a good game from start to finish. I think the first goal was the turning point," he said.
"In the second half, when we made it 3-0, we could see the game out.
"What I liked in this game is that at half-time we were sure we could end as winners.
"We were not nervous. There was a sense that the opponents couldn't equalise and that we wouldn't lose our lead."
