Hector Bellerin insists 3-4-3 formation suits Arsenal's style of play

Hector Bellerin has saluted Arsene Wenger's decision to use a 3-4-3 system as he believes the formation suits Arsenal's style of play.

Wenger has rarely strayed away from a traditional back four during his tenure in north London.

But the Gunners' bout of poor form earlier this month forced the Frenchman into a defensive reshuffle.

Arsenal have responded with three consecutive victories against Middlesbrough, Manchester City and Leicester to reignite hopes they can finish the campaign strongly.

Bellerin has featured as a right wing-back within the new system and believes he and his team-mates fit the formation well.

"For the style of play that the team has, it works really well," Bellerin told Arsenal's official website.

"Sometimes you’ve just got to keep switching system and make the other teams just think about it for a second and I think the team is doing really good.

"No matter what system we play, I think the team is performing so we’ve just got to keep it going and enjoy every minute of it."

Arsenal travel to Tottenham this weekend for what is expected to be the final north London derby played at White Hart Lane.

Such an historic occasion will ensure there is added motivation for both sides and Bellerin believes Arsenal are set to go into the game in good spirits.

"It’s really important to get to those games with a good spirit and good mood in the dressing room and after these two last results, the team is in a great one," the Spaniard added.

Meanwhile, Wenger is unsure whether Laurent Koscielny will be able to shake off a knee problem ahead of Sunday's trip to Spurs.
