Chelsea skipper John Terry hailed goalkeeper Petr Cech after his cleansheet in Barcelona.
"Big Pete made some great saves. It was great to see him back in tip-top form," said Terry.
"Over the last few weeks he has been back to his very best and that has been massive. You go through periods in the season when you are not at your best.
"But it is good we have got such a good bunch of lads around to push you on."
