He scored a couple and set up the other against them when Watford ended their world record breaking*, bestest everest in the world ever*, and surely worthy of an iron on tin-foil badge on their kit*, run of being undefeated ever*, near the end of their all known record breaking season* earlier this year.
Maybe he impressed Bingo in that match, maybe they're going down the un*t*d transfer policy route of "if he plays well against us he must be good, lets buy him", who knows.
+ q way, he's probably best described as "not absolutely shit" but he aint all that IMO and only got 5 goals all season for Watford.
(* all of these stats might be wrong but LFC and the UKMedia reserve the right to spout them as the truth, whole truth and nothing but the truth - until fact checked and then they'll spin it another way)
