His match-winning brace at Stamford Bridge followed a landmark 50th strike for the club, when he converted Daniel James's through ball during the 3-1 victory against Norwich City. After that particular feat, he asked fans on Twitter to guess his favourite goal from his first half-century for the Reds.
Understandably, he chose his derby winner at Manchester City's Etihad Stadium in March 2016, when the Reds clinched an excellent away success.
