Chelsea defender Marcos Alonso sees their clash with Tottenham as a must win in the top four race.

Alonso will not let go of his belief the Blues could still mount a late-season charge without victory in that game - but admits they will be up against it.

He said: "It is definitely a must-win game. Here at Chelsea, we have to fight until the end for every target we can achieve, and next year we have to be in the Champions League. On Sunday, we have to get a win.

"It's a massive game. We have a very important target, which is arriving at the end of the season in top four. Starting on Sunday, it's the first important three points for us.

"It's not over until its' mathematically impossible, but it would be very difficult for sure if we lost."
