Chelsea boss Roberto Di Matteo 'deflated' by Juventus after late drama upstages Oscar

Juventus cancel out young Brazilian's goals and snatch 2-2 Champions League draw

Roberto Di Matteo admitted that Chelsea were "deflated" after letting a 2-0 lead slip against Juventus last night. The Chelsea manager warned his players that they need to keep the ball better as the game ended 2-2.

"We feel disappointed and a little but deflated that we found ourselves in a fantastic position to win this game and we came away only with a draw," Di Matteo said afterwards. "They are always dangerous – they have a lot of quality in their team. We feel disappointed because we should have closed the game and brought the win home."

Fabio Quagliarella's equalised with 10 minutes left. Di Matteo was unimpressed with the concession, as Jon Obi Mikel was caught on the ball and Claudio Marchisio slid through the Italian forward. "I think we should have dealt with it a little bit better," Di Matteo said. "There was no pressure on the ball and it was pretty difficult to play offside. We lost possession just beforehand and we should have reacted much quicker to losing the ball than we did."

Despite winning the Champions League last year, Di Matteo knows that this is an area where Chelsea must improve. "In football, unfortunately, sometimes you give the ball away," the manager said. "We were a little bit under pressure but that's how it is. It is something that you try to improve all the time, to be composed in possession and to keep the ball better. We did during the game give the ball away a little bit too cheaply at times but I think we also played some good stuff tonight."

Di Matteo also condemned Portuguese referee Pedro Proenca for missing fouls on his players, the worst of which was a stamp by Leonardo Bonucci on Oscar, which Di Matteo described as a "bad tackle", midway through the second half. "The referee tonight did do nothing about many challenges," Di Matteo said. "The game has finished now for us. If Uefa has a look, then good. But we have to move on from it."

Eden Hazard was also denied a plausible penalty claim when he was tripped in the box. "It's a penalty," said a frustrated Di Matteo.

"He got pushed and there was contact as well. It is the second game in a row now that they [officials] seemed to not see it."

Di Matteo, though, was delighted with Brazilian debutant Oscar who scored two long-range first-half goals. "It was a great debut for Oscar," he said. "I thought it was the right game to start him and he did a perfect job tactically. He scored two goals and the second one was a wonderful goal."

There is much confidence in the 21-year-old, signed from Internacional in July. "He was perfect tonight with the tactical information we gave him. It is great to see that we have a player like that in our ranks," added Di Matteo.

"He is a big talent. He has got a bit of everything. We shouldn't forget that he is still a young man – he is only 21 – but he is already quite established in his national team already. I think we are very lucky to have him in our team."

Di Matteo praised the Italian side who improved as the game went on, especially after Arturo Vidal's first-half goal gave them hope of a comeback. "Juventus are a good team," Di Matteo said. "They have quality players. It was a tough game for us but I think both teams played really well.

"We are a little bit disappointed about the result obviously because we were in a good position but we didn't control the game."
