Arsenal travel to East Sussex to take on Championship side Brighton & Hove Albion in the fourth round of the FA Cup at the Falmer Stadium.
Since their 0-2 defeat to Southampton on New Year's Day, the Gunners have been in pretty good form, recording back-to-back wins in their last three fixtures.
The North London club will especially be bubbling with confidence following their 2-0 Premier League win over defending English Champions Manchester City in the last fixture.
However now the Gunners face a completely different test in the form of Brighton & Hove Albion as they look to successfully retain the FA Cup title.
Considering Arsenal's recent run of form, they are expected to breeze past Sea Gulls, but Arsene Wenger's men will be a little wary of the Championship side after watching the likes of Manchester City and Chelsea getting knocked out after losing to lower division teams on Saturday.
And Arsenal boss Wenger despite making claims of his side being confident after beating City, admits that his side will be under pressure "to repeat that kind of performance" on Sunday.
"[Beating Man City] raises the belief and the confidence of the team but it also questions your ability to repeat that kind of performance, and to keep that consistent tenacity in your concentration," the Frenchman told Arsenal's official website.
"That's what will be questioned on Sunday at Brighton. Let's show that we can produce exactly the same level of focus and the same dynamic in the team."
Wenger will probably be tempted to start with the same squad (that beat City) against Brighton on Sunday, but the return of Theo Walcott and Mesut Ozil will probably prompt the Frenchman to make some changes.
Also, Danny Welbeck will be missing the game due to a thigh strain, and the injury woes of Alex Oxlade-Chamberlain (pelvis) and Hector Bellerin (ankle) make them doubtful starters.
And Wenger despite admitting that the core of his side would remain the same revealed that other players would also be getting an opportunity on Sunday.
"Many of these players [who played against City] will play, but it will absolutely be the first-team squad, a top-level squad. There's big competition at the moment for places in the team, and some players will have an opportunity to show that they are ready to play again."
Meanwhile, Brighton & Hove Albion will also be fancying their chances against Arsenal after seeing some big Premier League teams getting eliminated by lower division sides on Saturday.
Although the Sea Gulls, who finished sixth in the Championship in the 2013/14 campaign, have not been in the best of form this season, they have been doing well of late, having registered five successive wins after their draw against Reading on Boxing Day.
And the Sea Gulls boss Chris Hughton feels that his side's current run of form will give them a boost ahead of their FA Cup clash against Arsenal on Sunday.
"It's definitely better going into this type of fixture in good form and with a good feeling. You have to be able to go into it with a game plan that gives you a chance to win or get something out of the game, but we all know the magnitude of the job," the former Norwich City boss told Brighton's official website.
However, Hughton admits that Arsenal are "better" than his side, and beating them, especially considering their current form would be a "very challenging task."
"It would be nice to see a real open, free-flowing game but the reality is they're better at it than us and they're better than 90 per cent of the teams at it," he added.
"Plus, they're a team in very good form so it makes it a very challenging task but we will enjoy it as much as we can."
Still the 56-year-old boss is confident that they will be able to do well if they manage to "nullify" the Gunners' strengths on Sunday.
"It's our responsibility to try and do the best we can to nullify their play and the areas that they can really hurt us, to give us a chance of winning the game," he added.
