Busquets wary of repeat of Chelsea’s Nou Camp heroics in 2012

Sergio Busquets has warned his Barcelona team-mates that the best team does not always go through in the Champions League.

Barca have not lost at home all season and Chelsea have been defeated in their last four away games.

The second leg also pitches La Liga’s leaders against fifth in the Premier League but Chelsea have got the better of Barcelona over two legs before.

In 2012 they managed a 2-2 – a result that will see them through tomorrow – and after winning the first leg 1-0 win at Stamford Bridge they went through to the final.

‘It was a sad night for us,’ Busquets said. ‘We scored early and then got the second goal but then they scored and that changed everything.

‘We did everything but score a second goal. We won a penalty but missed it. We couldn’t believe that after all the chances we had we did not go through to the final. Sometimes the best team doesn’t win.’

Busquets, Paulinho and Ivan Rakitic will be three of four midfielders to face Chelsea on Wednesday. The the fit-again Andres Iniesta, and winger Dembele are the other names in the frame for the remaining two places.

‘Dembele is fine. Everything is new for him but he is young and he will adapt. And he’s a player who can make the difference regardless of whether he starts or he comes on to make an impact,’ Busquets said.

‘Iniesta is our captain and a player who brings something different. He creates chances and he gets away from people. We hope he plays. He is back in training,’ he added.
