Arsene Wenger has fired a warning to 4th placed Tottenham - and says his Arsenal side will do everything they can to overhaul their north London rivals in the race for Champions League football.
The Gunners sit four points behind Spurs in 5th place, with both sides picking up maximum points over the weekend.
A Gareth Bale-inspired Tottenham forced their way past Newcastle at White Hart Lane before Arsenal responded with a hard-fought 1-0 win away at Sunderland.
Last season, Harry Redknapp's Tottenham blew a 10-point advantage over Arsenal, eventually finishing fourth behind their rivals and ultimately missing out on Champions League qualification.
Now under Andre Villas-Boas, Tottenham are in a similar position and have the upper hand over Arsenal with 12 games of the Premier League season to go - but Wenger believes there is still plenty of time for his side to reel their rivals in.
'There are many games to go,' Wenger told Arsenal Player when asked about his team's attempts to catch Spurs.
'We are in the fight and the game on Saturday showed that we are ready for a fight.'
Arsenal kept the pressure up on Tottenham with victory on the road against Sunderland, but had to do it the hard way after Carl Jenkinson was shown his second yellow card of the game after 62 minutes.
The Gunners clung on to three valuable points despite a late Sunderland ambush, and Wenger believes his side's demonstrated character that will stand them in good stead in the top-four race.
'Our character was questioned many times,' the Arsenal manager added.
'You saw (on Saturday) that we have plenty. I liked the last 20 minutes when we were pushed back. We headed every single ball. We tried like mad and that's fantastic to see.
'Sometimes you have to just dig in and some players played in uncomfortable positions. When we have the desire to win, it helps a lot.'
