Arsène Wenger’s men spurned the opportunity to all but cement their grip on third spot after suffering a surprise defeat by Wigan Athletic last week, before being held to a goalless draw by Chelsea on Saturday.
Arsenal were given a boost in their race for a top-three finish when Queens Park Rangers beat Tottenham Hotspur at Loftus Road, leaving the Gunners six points ahead their north London rivals and three ahead of Newcastle, who both have played a game less.
“It will be a big effort for everybody to get that third place,” Vermaelen told Arsenal’s website. “It is not going to be easy but that is because you play in England and it is not an easy league.
“Everybody can beat everybody. It is going to be hard to keep third place but I am confident that we will.
“Of course [it is going to be interesting] because there are a lot of teams involved; ourselves, Tottenham, Chelsea and Newcastle. It is going to be tight but it is going to be interesting.”
“Against Wigan we started really badly in the game and I think the last two games we played to win. We didn’t and they were really good chances to put ourselves into third place comfortably. At the moment we still have to fight for third place.”
