Tomas Rosicky believes his goal against Tottenham on Sunday proves he can be the difference in the big games for Arsenal.
The Czech midfielder thundered Arsenal into a second-minute lead at White Hart Lane before helping the team produce a battling defensive display to grind out three vital Premier League points.
Rosicky was delighted to score his second goal against Spurs this season and feels the win will reenergise the Gunners' title charge.
Defensively we were very good but we have to improve offensively if we want to win the leagueTomas Rosicky
"I am not a big goal-scorer but I can score big goals," Rosicky said. "I would like to get on the score-sheet more but for me it's not easy.
"The team is more important so even if someone else scored I would be glad as long as we won the game. It means a lot because it is a derby and everyone knows how the fans feel about games like that so it is a great win.
"Defensively we were very good but we have to improve offensively if we want to win the league."
The 33-year-old, whose fine form this season saw him sign a new contract with the Club recently is looking forward to the title run-in and thinks Saturday's trip to Stamford Bridge could be decisive.
"It will be a vital game against Chelsea but still there are so many games to go so we don't know what will happen after that," he said. "It can change very, very quickly in two games and of course you talk about Chelsea and Man City but you have to talk about Liverpool as well.
"There are four teams there and it is absolutely exciting."
