Tomas Rosicky believes the title race will go down to the last day of the season after Arsenal kept up their challenge with a 1-0 derby win over Tottenham.
Rosicky's stunning early strike handed the Gunners all three points to move them just four behind leaders Chelsea and level with Liverpool who had beaten Manchester United earlier in the day.
Arsenal and Liverpool also have a game in hand over the Blues, who lost to Aston Villa on Saturday, while fourth-placed Manchester City are two points further back but have played three games less than Jose Mourinho's men.
"I think it's a great race for the fans as well as the players," Rosicky told Sky Sports 1. "I think it will be until the last game of the season."
Sunday's loss leaves Spurs seven points behind City in the race for a Champions League place but the Czech midfielder does not believe they can be written off yet.
"You cannot count them out, this is a very tough league, every game is very important and there is plenty of games still to go," he added.
Rosicky got the Gunners off to a dream start as he exchanged passes with Alex Oxlade-Chamberlain before firing a fizzing angled drive past Hugo Lloris into the top-left corner.
"It's one of the best," he said. "Against Tottenham obviously as well. I'm delighted by a goal like that and most importantly we won the game.
"It's a great result for us. These derby games are always very tough. It means a lot for us, obviously for our fans as well. We are delighted."
Laurent Koscielny also shone at the back for Arsene Wenger's men and he believes that they need to maintain their workrate to stay in the title race.
"All the players who were on the pitch tried to give themselves for the team and to win because it's a derby and it's for winning," he said.
"We communicate well on the pitch - it's very important for a centre-back.
"When we work very hard on the pitch we can win so we need to keep this for the end of the season."
