Liverpool boss Jurgen Klopp says they must be wary of Watford with new manager Claudio Ranieri installed.

The Reds go to Watford on Saturday for the early clash.

Klopp said: "Claudio looks younger than me and he obviously has a good genetic basis.

"I think he has had probably had more than 15 clubs, so definitely more than I can, because I'm already 54 and I'm not sure I can catch up. I hope I'm still in shape as Claudio is now at 79, but we can only use the time we have in our hands and not think too much about 15 years time.

"When you look at their last game against Leeds when they lost, watford had a good idea about the game. They tried to build up with their football in wide positions, but the problem is when you lose the ball, the opposition has more space for counter attacks. That is why leeds won.

"Claudio said he wants to close the spaces. It is six years since I came new to the club but I wanted to give stability. You want to start by making them compact and that is what we expect.

"If it is completely different, we have to deal with that. I do not have a crystal ball so we have to guess a little bit."

He added: "It is harsh how Watford deal with managers. How can you be surprised they made a change? You learn the name of a new colleague and then they are replaced. I don't like this. Claudio (Ranieri)'s arrival makes things difficult, but we have to play our game."
