Jurgen Klopp has warned Europe's elite that Liverpool are back for good as he prepares for the club's first Champions League semi-final in a decade.
Few expected Liverpool to make the last four of club football's most prestigious competition and there is a feeling they may be left cursing their luck if they do not take advantage of a golden opportunity against Roma.
Klopp, though, believes the tie - Liverpool's first at this stage since Chelsea beat them in 2008 - is a sign of things to come.
It is why he will not be telling his squad to make the most of these games as he expects more nights like this in the future.
