Terry is convinced they're in the right frame of mind to take on Barca.
He said: "It's a very good achievement to reach our sixth semi-final in nine years, but we want to go through to the end.
"Clearly, that's going to be tough against Barcelona, but we're playing well.
"I am not sure anyone will fancy playing us at the moment because we are a very good side, especially in this competition.
"Barcelona are a very good team, but home and away we're a very solid side as well.
"We have shown that away against a very good Benfica side and proved on big nights at Stamford Bridge that we can really upset teams as well.
"We're confident. It is important we keep this momentum because we're going well in the league. That is the key for us."
