LIVERPOOL, Feb 22 — Jurgen Klopp said his injury-ravaged Liverpool produced “fireworks” to come from a goal down to beat Luton 4-1 and open up a four-point lead at the top of the Premier League on Wednesday.

Chiedozie Ogbene had given the Hatters a shock first-half lead against a Liverpool side missing Mohamed Salah, Darwin Nunez and Diogo Jota among others.
