Newcastle United manager Steve McClaren is positive about his squad ahead of their of the tie against the Gunners.
The Magpies are currently in 18th position, and have failed to win any of their last three games, losing to Tottenham and West Ham and sealing a point against Aston Villa.
"I'm really positive about the squad we have," he revealed, Newcastle United's official website reports.
"At any level, you need to be optimistic and positive as a manager - you need to believe in your players.
"It's a great group to work with but they are young and still learning things and I think they have been improving as the season has gone on.
"I've never been so frustrated and disappointed for the players as I have been in the past three games," he continued.
"They've given everything in those games and they haven't deserved to get the results they've got, but they need to take their chances. We've only scored one goal in three games where we've created plenty of chances.
"There's 19 games to go so we're not worrying just yet - I would be worried if the players weren't committed or weren't creating chances, but I think we've just been unlucky.
"We should have killed the game off (against Aston Villa), we had a stone wall penalty shout (against West Bromwich Albion) and the game before (against Everton) we conceded right at the death. We've been unlucky in those games, but you often find these results even themselves out over the course of the season.
"Some of the games we've played, the results have been disappointing but the performances have been there - if we take that level of performance, we'll win games.
"We need to maintain a positive mentality. We can't wallow in defeat or celebrate too much in victory because the next game is just around the corner.
"We're professionals and we have to deal with this sort of thing and we have to bounce back on Saturday against Arsenal.
"It's a long season, it's important the team stick together, be strong and be ready for the second half of the season in 2016."
