Arsene Wenger has stated that the duo of Odion Ighalo and Troy Deeney will be a handful when Arsenal entertain Watford in Sunday's FA Cup quarter-final tie at the Emirates.
Ighalo who is experiencing a goal drought lately, has netted 14 Premier League goals in 29 appearances.
Deeney has found the back of the net eight times in the same number of games as Ighalo.
And ahead of Sunday's clash, Wenger told arsenal.com that his central defenders will have to put in a top performance to contain the two strikers.
"They have two strikers who are very efficient in Ighalo and Deeney and we worked very hard to control the game (llast time we played them),” Wenger said.
“They have a very good understanding between their strikers and the quality between our two centre backs will be vital on Sunday.
Wenger added: "The difficulty (for us) 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.”
The last time both teams met in the league last year, Arsenal won 3-0 at Vicarage Road.
