The former Blues defender took to Twitter to voice his views on the Champions League semi-final first-leg at the Vicente Calderon as part of Heineken's 'Share The Sofa' campaign
Diego Simeone's men tried their utmost to bag a vital win in the Spanish capital, but they were eventually unable to break down the guests' defence.
Former Blues right-back Juliano Belletti was left breathless at full-time after tweeting throughout the encounter as part of Heineken's 'Share The Sofa' evening.
Goal compiled a list of our favourite tweets from the Brazilian during and after the game, as he talked Diego Costa, Thibaut Courtois, Jose Mourinho and Fernando Torres...
Belletti on Atletico Madrid
"This is a different Atletico than against Barcelona - they've got lots more space to play in."
"Ironic that the keeper who would normally be in the Chelsea goal now is in the Atletico goal."
"Atletico is looking aggressive but it hasn't paid off... yet."
"It's strange to see Atletico so desperate - they've got 90 minutes more to score goals."
Belletti on Chelsea
"Think Chelsea will play a tactical game tonight. Mourinho is looking for the draw."
"Chelsea are playing for position - not closing Atletico down. It's all about patience and pounce on Atletico's mistakes."
"Even Torres is helping out in defence now - very clear what their game plan in."
"This result really makes Chelsea the favourites for next week. And makes me wish I could be there to watch them."
BELLETTI ANSWERS GOAL'S QUESTIONS
Do you think Cech could lose his starting berth at Chelsea to Courtois next season or will he remain their No.1?
Diego Costa has been unable to break down the Chelsea defence by himself so far, time to bring on another attacker?
Belletti: "Chelsea defence is so hard to break through. If Atletico want to score they need to keep pressure."
