Liverpool will be glad to see the back of Nottingham Forest. Two games against the big surprise of the Premier League season have yielded just one point for the leaders after their 1-1 draw at Forest’s rocking City Ground on Tuesday. Liverpool has lost only once in 20 games so far this campaign — and that was 1-0 at home to Forest in September. Four months later, Diogo Jota scored with a header from a corner in the 66th minute — just 22 seconds after coming on as a substitute — to earn Liverpool a draw that maintained its six-point cushion over Forest, which moved into second place in its improbable bid to qualify for the Champions League. And who knows, maybe more.
