Arsenal defender Laurent Koscielny says they have the steel to grind out decisive victories as they chase the title.
The Gunners go into FA Cup fourth-round weekend a point ahead of Manchester City and two clear of Chelsea following their 2-0 win over Fulham.
"We can't play 100 per cent all the time in the way we play, so there will be some moments in some games where we lack quality, where it will be more difficult, where it won't be pretty football, but we stay strong, we graft and we never give up," Koscielny said in the March edition of the official Arsenal magazine.
The France international continued: "Mentally we are stronger than ever. We have won some games this season that we would never have won last season.
"It [the spirit] was always there, but more perhaps towards the end of the season.
"We can feel this season there is something special in the squad. We have all understood that we can achieve something together."
