Arsene Wenger outlines what he thinks will be difficult against Watford

Arsene Wenger In Emirates Press Conference 2

The Arsenal boss says his centre-back pairing will need to be on top form to contain Troy Deeney and Odion Ighalo in this weekend's FA Cup quarter-final.

Arsenal manager Arsene Wenger has told the club's website that he is expecting a tough challenge against Watford in the FA Cup quarter-final this weekend, and says his centre-back pairing will need to be on top form to contain Troy Deeney and Odion Ighalo.

The Gunners host the Hornets on Sunday as they look to continue their bid to become the first club to win three successive FA Cups since Blackburn Rovers in the 1880s.

Wenger's side beat Quique Sanchez Flores' men 3-0 in October, but the French boss is expecting a much tougher test this time around despite the promoted side having failed to win any of their last three matches.

The 66-year-old told the club's website: "They have two strikers who are very efficient in Ighalo and Deeney and we worked very hard to control the game [last time we played them].

"They have a very good understanding between their strikers and the quality between our two centre backs will be vital on Sunday.

"The difficulty is that Watford have a team who are very solid defensively. They are also a team who are athletically very strong and the basis of their game is on efficiency and waiting for the right moment to be very dangerous."

Wenger is right to highlight the danger posed by Deeney and Ighalo; the Watford frontmen have struck up a lethal partnership this season, scoring 24 goals between them since the club's promotion from the Championship.

Not only do the Hornets pose a potent threat, but only three other Premier League sides have conceded fewer goals in 29 league matches this season than Watford's 30.

Arsenal head into Sunday's quarter-final off the back of a 4-0 victory over Hull City in their fifth-round replay in midweek.
