Speaking ahead of tonight’s Champions League semi-final second-leg against Roma, Ferdinand said Firmino was crucial to Liverpool’s chances of defending their 5-2 first-leg win.
“This front three of Liverpool, there aren’t going to be any surprises tonight,” Ferdinand said.
“You know what to expect, but in this day and age speed kills. They’ve got it in abundance.
“What they’ve got as well, the catalyst for everything going forward in this Liverpool team, is Firmino.
