Crisis gave way to a fresh sense of optimism at Arsenal prior to the international break with three defeats in six soon forgotten as the Gunners brushed aside Manchester United 3-0 at the Emirates Stadium.

Three goals in 19 stunning minutes in north London saw Arsene Wenger's side move up to second place in the Premier League, just two points shy of leaders Manchester City.

Back-to-back defeats in the Champions League have left Arsenal teetering on the brink of an early exit with a double header against Bayern Munich to come in matchdays three and four.

Boasting the second best away record in the league, the Gunners will provide a stern examination of Watford's well-drilled defence at Vicarage Road on Saturday evening.

But who are the men to look out for in Arsenal's ranks?

Hector Bellerin: With stellar names such as Mesut Ozil and Alexis Sanchez available to Wenger, the pacey Spanish full-back might not seem the most obvious threat to the Hornets but he has created the most chances in the Premier League.

The former Barcelona youngster spent eight games on loan at Vicarage Road during the 2013/14 season and despite impressing, his rapid ascent at Arsenal has been remarkable.

First choice at right-back for much of this campaign and last, Bellerin only made his first Premier League appearance for the Gunners a year ago tomorrow but has already seemingly moved ahead of Mathieu Debuchy in the pecking order.

Bellerin scored twice for the north London giants last term, against Aston Villa and Liverpool, before ending the season an FA Cup winner as Arsenal swatted aside a Villa team managed by former Watford midfielder Tim Sherwood.

Santi Cazorla: The Spanish maestro will be no stranger to Hornets head coach Flores after plying his trade in La Liga for nine years before moving to the Premier League in 2012.

The 30-year-old playmaker started his professional career Villarreal in 2003.

After a single season with the Yellow Submarine's second string Cazorla soon made his mark on the first team and twice won the UEFA Intertoto Cup before moving to Recreativo in 2006 for just €600,000.

A stunning year with the El Decano saw Villarreal activate a clause to bring him back for just €1.2 million. That proved a bargain and he spent four more years at El Madrigal before moving to Malaga for €21 million.

He would spend a single season with the nouveau-riche club before being brought to the Emirates in a £16 million deal. That fee has proven value for money once more with a return of 27 goals in 156 outings in all competitions.

Capable of playing as a deep-lying playmaker or as a more conventional wide midfielder, Cazorla has no preferred foot - just another complication for opposing defenders.

Theo Walcott: With seven goals in his last nine games for club and country, Walcott is threatening to finally flourish as the centre-forward he has always backed himself to become.

Used predominantly as a right winger following his £12 million move from Southampton as a teenager, Walcott looks to have finally persuaded Wenger he can hold his own playing as a striker and scored in the Champions League defeat by Olympiakos and the 5-2 thrashing of Leicester City prior to the international break.

The lightening quick 26-year-old built on that form by scoring for England in a 2-0 win over Estonia last Friday, just his eighth goal for his country after earning a shock first call-up to the 2006 World Cup in Germany - despite having just 13 senior appearances to his name at the time.

He did not feature at that tournament but manager Sven-Goran Eriksson had clearly identified something in the prodigious youngster.

And as he matures, questions over his composure and end product are gradually abating.
