I recall Huckerby got 2 hattricks in successive games, but cannot remember if they were both in the league or if one was in the first round of the FA Cup(against Macclesfield maybe???)
Dion (v Chelsea, opening day of 97-98 season), Huckerby (one of those aforementioned games at least), Quinn (v Arsenal, opening day of 93-94 season...I remember heading down to Devon in the sweltering heat of the M5 when those sports reports were coming through), Ndlovu (v Liverpool in front of the Kop) are the only ones I can think of.
Have any of the above scored more than one hat-trick in the Premier League...if Huckerby did not get consecutive hat-tricks in the league? I seem to remember seeing an article saying that Micky Quinn was the most prolific striker in his first ten games in Premier League history, so maybe him and Dion have two??
