The possibilities seemed endless for Luis Diaz at Liverpool the last time Tottenham Hotspur travelled up the M6 to Anfield.
Almost 12 months ago, Diaz had cemented himself as one of the signings of the season, a rare case of a player arriving in the Premier League midway through a campaign and having an almost instantly devastating effect.
Diaz had already started the League Cup final win over Chelsea less than two months into his time at Liverpool, and was looking forward to an FA Cup date against the same opponents the following weekend having just days earlier come off the bench at half-time to turn the Champions League semi-final second leg in favour of the Reds and set up a showpiece with Real Madrid.
