After two convincing victories over Italian opponents, Chelsea were set to face their toughest opponent yet: Spanish giant Real Madrid.
Madrid, led by superstar Cristiano Ronaldo, would undoubtedly play at an entirely different level than Inter and AC Milan did when they came up against the Blues.
The match offered plenty of subplots, namely Mourinho coming up against his most recent club.
After a seemingly-even opening, Madrid started to truly show their class.
Holding most of the possession, Los Blancos found a way through in the 14th minute, when Brazilian left-back Marcelo managed to fire a shot through Cahill's legs and into the bottom-right corner of the net.
Minutes later, Chelsea offered a quick response. Ramires, who was fortunate, got in behind Madrid's defense and lifted a deft chip over goalkeeper Iker Casillas to tie the game at one.
It was clear that Madrid were the better side on the night. They deservedly regained the lead in the 31st minute on a brilliant, yet typical Ronaldo free kick. Madrid went into halftime leading 2-1.
Things were different in the opening minutes of the second half, where Chelsea looked like a completely different team. The Blues pressured Madrid high, and looked like a more threatening side, doing well to keep better possession. Hazard almost tied the game once again, only to be denied by Casillas on a breakaway.
However, the Blues were a bit unlucky to see Madrid double their advantage after Ronaldo found space in a ball-watching back line to head home a brilliant cross.
The 3-1 lead stood to hold, and left Madrid as 2013 International Cup Champions.
First, let me start off by saying that there is no shame in losing to Real Madrid, especially in the preseason.
But, Chelsea just didn't look in the same league as the Spanish side.
Constantly being out-possessed, the Blues seemed to be chasing shadows at times during the match. Furthermore, Chelsea's back four was constantly caught ball-watching, no time more obvious than on Ronaldo's second goal.
On the offensive side of the ball, Hazard and Frank Lampard—who was making his first appearance of the preseason due to an Achilles injury—seemed non-existent for the most part. Additionally, Romelu Lukaku and Fernando Torres were too on their own during the match, making it difficult for either of them to get involved and make an impact.
Yes, it is only preseason. And, of course, they were up against one of the world's best in Real Madrid. While it is obviously not time to question Mourinho or doubt Chelsea's status as EPL contenders this season, it was clearly not a convincing performance for the Blues.
While Chelsea have as youthful and as talented of a side as any in the world, Wednesday's game versus Madrid showed that the Blues are just not experienced or mature enough to compete with the world's elite...yet.
