TEAMtalk takes a look at how Roberto Di Matteo may just have sealed the deal as Chelsea's next permanent manager after victory over Barcelona.

Frank Lampard might have got it wrong.

Roberto di Matteo might not have made Chelsea into Chelsea again.

After Wednesday night's sensational Champions League semi-final defeat of Barcelona, the Italian is two wins away from making them much more than they were before.

When Roman Abramovich turned to Di Matteo to steady a Chelsea ship that had listed so badly under Andre Villas-Boas, it appeared slightly desperate and very short-term.

Popular as a player, Di Matteo's previous management stint ended so badly West Brom put a call out to Roy Hodgson to save them from relegation.

The laughter echoed across the whole of football. Abramovich might have wealth beyond measure, but no idea about the game in which he has invested so much.

Three games into Di Matteo's reign, as John Terry stood in the technical area and barked orders to team-mates after being substituted against Napoli, the joke got a whole lot more amusing.

Confirmation of what we knew all along; JT is the real manager at Stamford Bridge no matter what the sign on the door might say.

Well, no-one is laughing now. Whether by accident or design, Abramovich might just have found the ideal man to run his team.

Di Matteo has been imposing his authority quietly but effectively.

He has restored a sense of unity to the camp, brought those frozen out back in from the cold and fallen back on the approach that brought success under Jose Mourinho.

But Di Matteo has his own ideas and plans. And tonight, much as Jose Mourinho did with Inter Milan in 2010, he delivered the perfect template for how to play against this brilliant Barcelona team.

Defend deep and in numbers, counter-attack quickly and hope for a little bit of luck.

All sorts of theories have been espoused about how to stop Barca.

Surely it has become obvious now? You can't.

What you do instead is limit their threat and cross your fingers that when Messi goes on one of those magical runs, or Xavi cuts a crossfield pass 50 yards deep into your penalty area, a mistake, a tackle, the woodwork, misplaced shot, Petr Cech save, Sergio Busquets skier, anything, stops it reaching fruition.

Then, when the maximum number of players are committed to attack, you hit them, fast and direct, exposing the frailties of a defence so secure in those ahead of them Javier Mascherano can play at centre-half without ruffling a hair.

As Abramovich applauded Didier Drogba's goal, he might have reflected that the joy came not from scoring against a team that played like Barcelona, but were Barcelona.

Rumour has it that the Russian wants Pep Guardiola as his manager because he can transpose the Catalans' image on Stamford Bridge.

He can't. No more than appointing Mario Zagallo would have made them play like Brazil circa 1970. To do that needed Pele, Jairzinho and Carlos Alberto, just as to be Barcelona requires Messi, Xavi and Andres Iniesta. Otherwise you have Swansea, pleasing on the eye but not quite the same.

So, within the limits he was working to, Di Matteo got it exactly spot on. One dark suited, slightly balding southern European with closely cropped hair overcoming another.

The irony that Messi should be the man robbed by Frank Lampard to set the move in motion for the winner could not be ignored.

From then on, it was sublime. The pass sprayed out wide. The speed of Ramires' run, catching the attacking Dani Alves a couple of yards too far upfield, the cross, rolled behind hastily retreating defenders, and the finish, first-time and to the corner.

At the start, Didier Drogba had already served notice he could cause his opponents' problems. If the 34-year-old had the pace he possessed six seasons ago, he would probably have scored.

Father Time does not diminish the eye for an opportunity though - and there is a reason why Victor Valdes' is Spain's number three keeper rather than their best.

And so it ended. No matter Barca dominated possession, that Messi danced and dazzled with the ball stuck to his left foot as though it were fixed like a piece of string.

The bad news for Chelsea is that only half-time has been reached. The good that the gap to next week's return is filled by El Clasico, in which every sinew must be strained if La Liga is not to be surrendered to Mourinho and the enemy in Madrid.

Chelsea have their own derby business to attend to, against Arsenal.

However, suddenly there are no knowing smiles if it is suggested that winning the Champions League might be the best way for the Blues to reach next season's competition.

Nor that Di Matteo is the right man to lead them there.
