Chelsea's Champions League run has been one of the best in recent history. From start to finish, Chelsea has kept spectators on the edge of their seat.
First came Chelsea's must-win match vs. Valencia in the Champions League group stage. If Chelsea had failed to beat Valencia, they could've seen themselves dumped out of Europe at the first hurdle.
Then came the Round of 16 matchup vs. Napoli. In the middle of one of their worst spells of form of the season, Chelsea were badly beaten by Napoli in Italy, three goals to one.
That away goal gave Chelsea hope, though, and under new coach Roberto Di Matteo, Chelsea were able to orchestrate a remarkable comeback to progress to the quarterfinals.
When Chelsea reached the semifinals, even Chelsea fans prepared themselves for the end. No way was Chelsea going to keep Barcelona from scoring for 180 minutes.
But Chelsea did what until recently even Real Madrid have struggled to do: they beat Barcelona.
Not only that, though, but they did it after conceding two goals and going a man down in the first half of the game at Camp Nou.
Clearly, this Chelsea team is nothing like the one that was playing under Andre Villas-Boas earlier this season. This is a Chelsea team made up of leaders and men of true grit and personality.
Unfortunately, all heroic tales must eventually come to an end, and for Chelsea, that end will be a bit premature, as it will be before they lift the Champions League trophy. Here are the five reasons I don't believe Chelsea will be able to go all the way this year.
