Manchester United striker Marcus Rashford is set to miss Sunday's Premier League trip to Liverpool through illness.
Rashford, 27, was left out of manager Ruben Amorim's squad for four games, initially due to his poor performance in training and his attitude around club colleagues.
Amorim brought Rashford back into the fold for the home defeat by Newcastle on 30 December, only to leave him on the bench as United suffered a fourth consecutive defeat and third successive game without a goal.
Serie A title contenders Napoli are the latest club to be linked with Rashford, who United would be willing to move on loan if his wages, in excess of £300,000-a-week, were covered.
