Liverpool headed to Manchester on the front foot ahead of their deciding tie against Manchester United in the Europa League Round of 16, having defeated their arch rivals at home 2-0 last week, but Jürgen Klopp was dealt a late injury blow during training at Old Trafford when Alberto Moreno became the latest player to succumb to a hamstring injury.
The club insisted it was "too early" to determine whether the pain Moreno experienced was enough to rule him out of the tie all together, but given the number of hamstring injuries Liverpool players have suffered from this season, it wouldn't be shocking if Moreno ended up watching from the sidelines while those with fully intact tendons put in a shift on the pitch.
Waiting in the wings will be Brad Smith, with Jon Flanagan ineligible for Europa League action having not been named to Brendan Rodgers' squad while injured nor when Jürgen Klopp made three additional changes prior to the start of the knock out rounds. There is, of course, the possibility that Klopp finds an entirely different solution given the number of midfielders and centre backs at his disposal who have been awkwardly shoehorned into either fullback position at various points in their careers.
The club have neither confirmed nor denied that Moreno's hamstring tweak had anything to do with the other totally safe and not at all ill-advised activities he gets up to in his spare time.
