Theo Walcott scored for the Gunners in the opening minute of the 1-1 draw with Everton at Goodison Park before the Toffees got on top after Marouane Fellaini’s 28th minute equalizer.
Vermaelen was full of praise for his Arsenal teammates for grinding out a result and suggests that the mindset of the squad is currently very strong.
"Mentality-wise, there is nothing wrong with the team," Vermaelen said on Arsenal Player.
"Everybody works hard and there is no-one who doesn't work for the team, and that will give you results, from that point of view I am very happy.
"In the first minute we scored a good goal, and after that we dominated, but gave them chances because we were a little bit sloppy with the ball, so that was a bit disappointing.
"In the second half we were a little bit dangerous, but didn't create too many chances.
"In the end we got a point, I don't know if we should be happy with that or not."
