Mikel believes their comeback will prove the turning point in their season.
He said: "The character we showed in the second half is something we can keep going.
"Let's hope this is the performance that puts us back in a good place and we can keep going and end the season well."
It was an incredible turnaround by Chelsea who were two down inside 11 minutes.
Mikel claimed the second-half display showed the real Chelsea, saying: "We are at our best when we are an attacking team.
"We have players who like to attack, who enjoy moving forward, who like to have the ball, beat people and create chances. And in the second half that's exactly what we went out to do."
