Chelsea head into next weekend’s game as the underdogs, as they face German giants Bayern Munich at the Bavarians' own Allianz Arena.
The Champions League has consistently been the one trophy that has eluded Chelsea and their Russian owner Roman Abramovich, and Mikel knows if they bring the silverware home they enter the club’s history books as legends.
The Nigerian midfielder told The Independent: “I had only just come into the club but after that I could see what the Champions' League meant to the players.
"And now we have a chance to put things right. We are now one week away from the greatest win ever for this club and we want to make history and be legends for this club.
“Hopefully on the 19th if luck and God help us we will make that history. If we can pull off this win it'll be the greatest achievement ever for this club."
Chelsea appear to be right up against the odds as they have only won one out of six away games in this season’s tournament, while Bayern have beaten the likes of Real Madrid and Manchester City at the Allianz Arena. However, Mikel believes the pressure of playing in front of their own fans could be a negative factor for the Bayern team.
He added: “We'll play with less pressure, have a chance to express ourselves and do what we want to do a bit better.
"We're gonna make sure we keep ourselves in the game, until the later stages. If we can grab a goal in the early stages it's gonna be good but we have to make sure we don't concede early.
“I think it'll be a very exciting game, a difficult game for us but for them as well.”
Chelsea go into Europe's showpiece event in the knowledge they will be without four first-team players in John Terry, Branislav Ivanovic, Ramires and Raul Meireles, who are all serving suspensions.
The 25-year-old knows it will be a hard task without those four men, but is hoping they can bring the trophy back to London for them.
Mikel remarked: “I think it's going to be massive missing John Terry, he's the leader. Everyone knows how he leads the team. Ivanovic as well – what a great player he's become over the years.
“What can I say about Ramires, he has been fantastic ever since he joined this club. Meireles as well.
“It is the biggest game of our life and I hope the players who step into others' shoes want to make this club proud. That's why we have to go in and make sure we win it for them and for the club."
