The midfielder believes his side were unlucky to lose out on away goals in last season's Champions League tie but is confident the team have greatly improved this termParis Saint-Germain midfielder Thiago Motta is determined to go far in this season's Champions League in order to put the "bitter taste" of last season behind them.
The French champions were knocked out at the quarter-final stage by Barcelona last year after a strike from Pedro at Camp Nou sealed an away goals win for the Blaugrana.
And having produced dominant displays in both the group stage and last-16 tie with Bayer Leverkusen, Motta is confident he and his team-mates are capable of overcoming Chelsea in the quarter-finals and challenging for the trophy this time around.
"When you're eliminated, it leaves a bitter taste in the mouth. I think we did a good job but in the end we were eliminated thanks to the goal from Pedro," he told BeIn Sport.
"This year we will try to do better than last time. We've changed a little bit. We've changed players, our game and our style of play. The team feels a little more confidence with how we play now.
"We're confident we're doing a good job. Things have certainly improved, we know that."
The first leg between PSG and the Blues takes place at Parc des Princes on Wednesday.
