Sead Kolasinac says Arsenal's plans this season are on track.

Arsenal can return to third in the table with victory at Sheffield United tonight.

“The Premier League isn't called the hardest league in the world for nothing," said Gunners defender Kolasinac.

“It [the race for the top-four] is pretty wide open. For example, Manchester City lost to Wolves before the international break. But we are just going to focus on ourselves and try to work hard to win every game. Who knows what will happen at the end of the season?

"We are still at the beginning now, but we hope to finish in the top four."
