Five things Chelsea learned from Germany's 7-1 thrashing of Brazil

Several Chelsea stars were in action in last night's historic World Cup semi-final. Here's what Jose Mourinho may have learned...

Life after Luiz

If Chelsea wrote a script for a World Cup that would totally justify their summer-sale of David Luiz to Paris Saint-Germain, it could not have gone any better than what has actually transpired in Brazil.

For a reported £50 million, any club would likely let the enigmatic 27-year-old go. But, if anyone had the slightest of doubts as to whether it was the right decision, they shouldn't anymore.

Against the Germans, Luiz was absolutely lambasted for his performance. As always, he tried his heart out, with statistics showing that he actually won more dribbles than any other player on the pitch.

But while Luiz's passion was unquestionable, his discipline was non-existent. Now it's clear for all to see why the wild defender is not Mourinho's type of player.

Oscar won't give in

Another positive for the Blues was Oscar's response to Brazil's thumping in the second half. Not many would blame the Chelsea midfielder for throwing in the towel at 7-0 down. But Oscar didn't, instead persevering to score a fine (yet meaningless) consolation goal late on.

That attitude would no doubt have impressed Mourinho - and could serve the 22-year-old well when he is finding game-time hard to come by, as well as when the Blues are trailing during matches.

Schurrle can make an impact

Andre Schurrle's talent is undeniable but the German forward can frustrate at times. He is an incredibly direct player who can cause any defence problems on his day. All too often, though, he goes unnoticed.

But Germany's 7-1 win over Brazil last night was not one of those times: the 23-year-old was simply superb after coming on, scoring twice - with his second an unforgettable strike.

Schurrle's form will pose a selection headache for Mourinho but, to use a cliche, it will be a good one. This served as a reminder of the impact the German can have coming off the bench.

Ramires off the pace

Unlike Oscar, Ramires didn't seem to cope well under the pressure of trailing by such a heavy deficit. Granted, he was replacing Hulk, so he was probably an upgrade just by being on the pitch.

The Blues midfielder looked lost after coming on for the second half, however, misplacing passes and awkwardly choosing to shoot when laying the ball off was a better option. Cesc Fabregas' arrival has upped the competition for places in Chelsea's midfield and, after a so-so World Cup, Ramires may find his spot in Mourinho's side under greater threat than ever.

If in doubt, use Willian

In the build-up to last night's semi-final, all the talk was about whether Willian or Bernard would replace Neymar. In the end, Luiz Felipe Scolari chose Bernard - but the move proved to no avail.

By the time Willian had come on in the second half, the game had been lost for what seemed like hours, rendering his impact futile regardless of how he actually performed.

Brazil have lacked fluency all too often in this World Cup and, had Scolari put his faith in Willian from the start, his side might have proved a lot more threatening going forward.

Of course, it would be ill-advised to blame Brazil's 7-1 loss simply on the decision not to start the 25-year-old. The fact that he has come out of this World Cup without looking too bad, though, is a slice of luck in itself for Mourinho given the circumstances.
