Good times ahead: Wenger hopes his side can fulfill their potential, starting with victory over Chelsea

Arsene Wenger insists the "moment has come" for his Arsenal side as they prepare to face Barclays Premier League leaders Chelsea at Emirates Stadium on Sunday.

The Gunners - who have a match in hand on their title rivals - will be looking to close an eight-point gap on the Blues after slipping further off the pace in the wake of last weekend's lacklustre defeat at Sunderland.

Confidence within Wenger's squad, however, remains high after they returned to winning ways with a 2-0 win over Standard Liege in midweek to book a safe passage through to the knockout stages of the Champions League.

'Everyone will look at the game to rate our potential, and I have no worries about that,' said the Arsenal boss. 'We are ready for the game, are well focused, prepared and the confidence is good.

'We just want to focus on the game like we want to play it.'

Wenger declared: 'It is a big test, yes - but that is what you want, to play these teams.

'I think there is a period for any team to come out and show its strengths. For my team, this moment has come.

'We are not any more a team that has to be considered to be young. 'I think we have the strengths and we can show that on Sunday that we are strong enough to compete.'

Arsenal, though, must take on the Premier League leaders still missing striker Robin van Persie and full-back Kieran Gibbs, while centre-back William Gallas is rated as only 50/50 to face his former club.
