Arsenal must ensure they strengthen in the January transfer window if they are to be taken 'seriously' as title contenders, according to the club's former striker Kevin Campbell.
The Gunners have been in sensational form since their opening day defeat against Aston Villa, with the north London club having won all nine of their games across all competitions following that encounter.
Arsene Wenger's side sit proudly at the top of the Premier League after six matches, two points ahead of second-placed Tottenham and eight points clear of defending champions Manchester United.
It is now down to the Arsenal to further reinforce when the transfer window opens again, says Campbell, if they have any serious ambition of maintaining their pursuit of a first trophy since 2005.
"They can challenge for the title but the key for Arsenal is what they do in the January transfer window,” he told talkSPORT.
“I think they could be there or thereabouts at Christmas and, if they could strengthen again, then you have to take them seriously.”
Arsenal will have the opportunity to extend their winning run into double figures when they host Napoli in the Champions League on Wednesday evening.
The Gunners beat Marseille in their opening group outing, while Napoli secured victory over last season's finalists Borussia Dortmund.
