The Reds conceded a 95th minute equaliser at Anfield.
Thiago said, "We have no words to explain the disappointment we have.
"The will to win, the desire to win is a very big part of the competition. We had a lot of chances to win in the first half.
"We tried to play our game. That was the key today. It worked very good in the first half, we created many spaces and created a lot of chances.
"It doesn't change that we want to win and want to be in the Champions League but for that we have to deserve to be there."
