Theo Walcott has warned Tottenham that Arsenal have them firmly in their sights after he set up the Gunners' winning goal in Monday night's 2-1 victory over Newcastle.
Thomas Vermaelen struck in the fifth minute of injury time after connecting with Walcott's cross as fourth-placed Arsenal moved to within one point of North London rivals Spurs.
Walcott was also involved in the first goal, setting up the Robin van Persie for the equaliser just 55 seconds after Hatem Ben Arfa had put Newcastle ahead.
And the England international was in bullish mood at the full-time whistle, as he told Sky Sports 1 HD: "Tottenham have got to be watching over their shoulders now.
"With the squad of players we've got - and we've got a lot of players coming back to fitness now - we believe that we can go much further.
"It's been an up and down season, but it's the way you finish, and that's the most important thing.
"We're just getting our jobs right. Defensively we've been fantastic. We know we can always score goals, but lately we've not been conceding too many, and that stat is fantastic."
The match marked the first time a team had come from behind to win in four successive Premier League matches, and game-winner Vermaelen added: "We showed the mentality of fighters. It's the fourth time we've come back from 1-0 down.
"In the second half, we were pushing and pushing. We knew we had to be patient and in the end we will score a goal, and that's what happened today."
