Liverpool boss Jurgen Klopp says he's never worked with a player like Roberto Firmino.
Firmino will play his 300th game for the Reds against Manchester United today.
"He is a connector; the best offensive defender I ever saw in my life. A very important player for us," said Klopp.
"He's a ball-chaser, incredibly smart tactically and able to play in the tiniest spaces; to make good decisions in really quick time.
"And on top of that he can score goals, which is why we are so happy when he rewards himself from time to time, like the hat-trick he got at Watford."
Klopp added: "Everybody loves it when Bobby scores because sometimes you think he is a bit short of getting praise for the effort he puts in.
"He is just a brilliant player and it really is a joy to work with him. It isn't impossible to play our way without him because we do have options but when we started this years ago it was because Bobby could play the role. So he was very influential in all the things we did."
