Frank Lampard says Chelsea's game against Tottenham next week will be crucial in deciding the outcome of the top-four race this season.
Chelsea face a difficult run of fixtures as they go in pursuit of Champions League qualification and Europa League glory, starting with their fixture against Manchester United on Sunday.
The Blues currently sit in 3rd place in the Premier League, with Arsenal in 4th and Tottenham in 5th and both hot on their heels with four league games to go.
Only three points separating the trio, with Tottenham and Chelsea's game in hand over Arsenal coming against one other at Stamford Bridge on May 8.
Lampard believes the fixture against Spurs next Wednesday, rather than the showdown with champions Manchester United, while have the biggest say on who will claim a precious Champions League qualification spot.
“I think it will go to the wire but if we get the right results against United and Tottenham we’ll put ourselves in a healthy position."
In between gunning for the top four Chelsea have the small matter of attempting to secure a spot in the Europa League final.
The Blues go into their semi-final 2nd leg tie against Basel on Thursday with a 2-1 advantage from the first-leg in Switzerland.
Lampard, who is one goal shy of equalling Bobby Tambling as Chelsea's all-time record goal-scorer after his strike against Swansea on Sunday, says he is aiming for success on all fronts in the final stages of the season.
“The Champions League is the test of the best and the main target," he said.
"But I want to win the Europa League as well."
