Arsenal can sustain their challenge for Premier League glory even without the acquisition of a reputable goalscorer during the January transfer window, according to the club's former left-back Nigel Winterburn.

The Gunners strived desperately to recruit a proven striker during the summer transfer window but proved fruitless in their respective pursuits of Gonzalo Higuain, who joined Napoli, and Luis Suarez of Liverpool.

Arsenal have, however, seen Olivier Giroud flourish in his position as the club's undoubted first choice centre-forward and the France international has found the net eight times to propel the club to the summit of the table at the start of 2014.

There has been an element of fortune though that Giroud has remained relatively injury free, with the 27-year-old's recent knock not expected to keep him out beyond the weekend clash with Tottenham in the FA Cup.

Winterburn does not believe the reliance on Giroud should necessarily prompt Arsene Wenger into the transfer market this month and expects the club to be involved in the race for silverware come the business end of the season if the Frenchman remains the key man in their armoury.

"They’ve gone a whole season with just Giroud and people are worrying about him getting injured because of the amount of games he’s got to play," he told

"We’re all guessing that playing a whole season as a lone striker will be very demanding and he’ll pick up an injury along the way that will keep him out for weeks or months, but that hasn’t happened yet.

"An additional striker would certainly help Arsenal, but just because they don’t bring somebody in doesn’t mean they can’t win the title.

"They’ve already proven they’re going to be there; whether they’re going to be good enough to sustain the challenge until the end of the season we don’t know.

"But they’re showing some good resilience and playing good football this season. They’re [top] on merit and they’ve played very well despite having a lot of injuries.

"I see them challenging right through to the end of the season."
