Roberto Martinez believes that it is still all to play for in this season's Champions League qualification race.
Everton closed the gap on fourth place with a 3-0 humbling of Arsenal earlier today and could leapfrog Arsene Wenger's side if they win their game in hand against Crystal Palace.
But Blues boss Martinez has refused to rule out the prospect of sixth-placed Manchester United, who are currently six points adrift of David Moyes' former club, and Tottenham Hotspur stealing in during the remaining five games of the Premier League season.
"There's still a long way to go, believe me. Today we won playing at home - we had that a little bit in our favour," he told his post-match press conference.
"Arsenal, from now until to the end of the season, have got 15 points to fight for and it's going to be a really tough and close battle.
"Even teams like Manchester United and Spurs, you expect them to have really strong endings to the season.
"We're delighted that we are in the mix, fighting for it and mathematically you can say that we are fighting for that aim."
Manchester United however sit six points behind Everton, having played one game more, but have to go to Goodison Park and a win for David Moyes' side could provide them with an opening if results go their way.
