The Blues missed a chance to cement a top four position on Monday.
Chelsea’s 2-2 draw with Burnley on Monday night was an opportunity missed for Maurizio Sarri’s side, says assistant coach Gianfranco Zola.
The Blues had a chance to cement a spot in the top four of the Premier League as they were held to a frustrating draw with Burnley, but they managed to leap frog Arsenal into fourth place.
Jeff Hendrick broke the deadlock with a lovely volley from the edge of the area in the 8th minute before the homeside responded with goals from N'golo Kante and then Gonzalo Higuain.
The Clarets then equalised in the 24th minute through Ashley Barnes as the visitors grabbed a vital point in their relegation battle.
"Certainly, with three points it would have been a different story," Zola said as the Daily Mail reported.
"We still gain a point on the other teams, and we'll not give up until the end. We tried everything on the pitch."
The Chelsea legend added: "We tried everything. It's not that we played badly. We created chances, but it's not easy to score.
"Maybe we should have done something more in the second half in their box, more effective and more precise, but the desire to win was there until the end.
"There was quality in the first half, but we couldn't get the rhythm going in the second half and breaking down a team like Burnley is difficult."
