Vitesse Arnhem vs. Chelsea: What Jose Mourinho Learned in Pre-Season Friendly
Diego Costa was the star of the show, setting up Mohamed Salah and Nemanja Matic to score their goals, while also winning the free-kick converted by Cesc Fabregas.
Indeed, the Blues continue to build for the new campaign, looking more and more impressive, and Jose Mourinho will be happy with how his team dominated the opposition.
We look at what the Blues manager would have learned from the game.
Diego Costa Cannot Wait for the Season to Start
We mentioned in the introduction slide that Diego Costa was the star of the show against Vitesse Arnhem, and his form since signing for the Blues has been impressive.
He scored on his debut against Olimpija Ljubljana on Sunday, and three days later, he proved too much for the opposition defence once more.
What impressed most about Costa was his attitude—pre-season friendly or not, he was determined to finish on the winning side and battled for everything, even coming to blows with the Vitesse defenders at one stage.
He may not have scored but was involved in all three goals, and he has the look of a man who is chomping at the bit for the new campaign to start.
Cesc Fabregas Is an Extra Outlet from Set Pieces
He may dance a mean Macarena, but Cesc Fabregas has shown himself to be equally talented when it comes to free-kicks.
Chelsea's second against Vitesse Arnhem was scored by Fabregas, who stepped to score a beautifully struck free-kick from the edge of the area.
With David Luiz and Frank Lampard now gone, it remains unclear who will be Chelsea's main set-piece taker.
A few more of those like we saw against Vitesse and Fabregas may well be given the responsibility.
No More Defenders Needed at Chelsea
Chelsea started the game against Vitesse Arnhem with Gary Cahill and Branislav Ivanovic as the central defensive pairing, with Filipe Luis and Cesar Azpilicueta at left-back and right-back, respectively.
At the interval, John Terry replaced Luis and Ivanovic moved to his more familiar right-back spot and Azpilicueta to left-back.
Cahill was replaced by Kurt Zouma late on, while Nathan Ake also appeared at left-back himself.
It showed the strength Chelsea have in defence.
They have versatility with Ivanovic and Azpilicueta, experience in Terry and the reliability of Cahill. Luis looks an impressive buy—despite the inflated price tag—and Ake and Zouma are encouraging youngsters.
Any fears the Blues may be weaker without Ashley Cole and David Luiz have been allayed.
Petr Cech isn't going to give up the No. 1 jersey without a fight
He didn't have much to do against Vitesse Arnhem, but whenever Petr Cech was called into action, he was more than up to task.
The Czech international faces a massive battle to maintain his position as Chelsea's No. 1 goalkeeper now that Thibaut Courtois has returned from his three-year loan spell with Atletico Madrid.
Right now, though, he has the look of a man ready for that challenge and impressed against Vitesse.
Jose Mourinho finds himself with two world-class goalkeepers available, and although he may face a few sleepless nights in deciding who he should pick as his preferred choice, it's a problem every one of his rivals would relish.
Chelsea and Jose Mourinho Do Not Need Romelu Lukaku and His Petulance
Some Chelsea fans may lament his sale, but Jose Mourinho would have seen enough from Diego Costa alone to know he will not miss the striker in the way many are predicting.
Lukaku may have scored goals while on loan, but the simple fact is that he never made an impact during his three years at Stamford Bridge.
Not once did he score for the Blues, and his attitude didn't bode well for working under Mourinho.
The Portuguese doesn't take kindly to his players speaking out against him or making demands through the media.
Lukaku made a habit of doing that, and Chelsea have now recouped an impressive profit on a player who did little for them.
They have a better, more experienced striker in Diego Costa, and while it was a pre-season friendly, the Spaniard showed against Vitesse Arnhem that he is going to slot perfectly into Mourinho's system.
