The 33-year-old Czech midfielder scored in the second minute of the North London derby to silence the crowd at White Hart Lane and win Arsenal three points against their arch rivals.
Manager Arsene Wenger has always showed great admiration for the attacker who has struggled with injury throughout his eight years at the Emirates and after agreeing terms to a contract extension to stay on with the Gunners past this summer. The veteran midfielder demonstrated exactly the kind of quality that makes him such an important figure for Arsenal.
The goal was indeed superb and could well be a contender for goal of the season but the three points were made not by the Czech’s contribution alone – a solid and formidable defensive display for the following 92 minutes at White Hart Lane ensured the Gunners continue on with their title challenge.
"It will go in my collection of great goals, I told Tomas that," Wenger said following the victory.
"It gets us a bit closer to Chelsea and makes the game next week even more interesting.”
"It is a four point gap and we have a game in hand. We will see what happens but the next game is a very big on,” he added.
Arsenal now face a trip to Stamford Bridge to face a Chelsea side that remain unbeaten at home under Jose Mourinho. The Gunners have a number of key players out injured and it looks unlikely that midfield ace Aaron Ramsey will return with Jack Wilshere and Theo Walcott certain to be out of the clash.
However, the quality and determination in the team, epitomised by Rosicky on Sunday will surely give the French boss reason for optimism that the Gunners can get a result against the Blues this weekend. A win would put Arsenal just one point behind the current Premier League leaders following Chelsea’s surprising 1-0 defeat away to Aston Villa on Saturday but a win against their North London rivals will surely be a huge boost for confident and morale ahead of the game that could decide their season in the Premier League.
