Jurgen Klopp says Liverpool are "completely on fire" as the Premier League title race hots up with just two matches to go.
Liverpool go to Newcastle on Saturday evening - live on Sky Sports - before title-rivals Manchester City face Leicester at the Etihad on Monday Night Football.
Despite a challenging fixture list that included Wednesday night's 3-0 defeat at Barcelona in the first leg of their Champions League semi-final, with the second leg to come at Anfield on Tuesday, Klopp insists his players are too focused on their efforts to win silverware to feel tired.

Klopp said: "The boys are completely on fire. When you are in the race and you see you can win it, you don't get tired, that's how it is. You get an extra boost and you find something.
"We are ambitious like hell but we still know it's not 100 per cent in our hands. The only thing we can do is beat Newcastle and that's unbelievably difficult.
"That is our problem, not what two teams [Manchester City and Leicester] are doing on Monday night.
"Our problem is how to find a way to beat Newcastle."
Liverpool controlled large parts of the game in the Nou Camp before eventually succumbing to the Spanish champions, and Klopp says their confidence has not been knocked going into the crucial clash at St James' Park.
"We are not too experienced in Europe but we have our own experiences and we do not stay too long in the last game, where we say 'we could have done this better, we could have done that better' - we don't have time for that," added Klopp.
"There are two ways you can think about the game: one was the result and one was the performance. From the performance you can take a lot, from the result you cannot take a lot.
"We have to try to sort this on Tuesday [the second leg against Barcelona] and not now. When we flew home, it was already OK, the players were already in the Newcastle game, 100 per cent.
"We did not have to pick up players in Barcelona and give them a hug. That's [resilience] in us and we know it. You cannot expect to go to Barcelona and be 3-0 up and have a 'holiday game' in the second one.
"It's not like this. In football, if you want to win everything, you need to accept you still can lose.
"With the performance, the players felt it on the pitch. We did some really good stuff there and we caused them problems.
"It was not enough for that night because we didn't finish it off. It's not very often that they lose 3-0 but we have much more positive thoughts about the game than negative. That's the truth.
"We now go to Newcastle and that is the situation the whole year, there is always the next one."
