The England international featured in both legs of our Carabao Cup semi-final with City in 2019/20, but wasn’t called upon in the back-to-back victories over the Blues in the Premier League.
He’s in with a great chance of starring on Saturday though, with the involvement of Anthony Martial and Edinson Cavani still unclear due to injury, and Greenwood looking refreshed and revitalised after a rest during November’s international break.
Mason netted his first top-flight goal of this campaign at the London Stadium last weekend, helping the Reds recover to beat West Ham United 3-1.
Because Greenwood’s lightning-quick turn-and-finish – which utterly bamboozled Hammers keeper Lukasz Fabianski – bore all the hallmarks of an established centre-forward, it’s easy to forget just how green our no.
