The England international has enjoyed mixed fortunes during his time on Merseyside. But despite cementing himself as England's first-choice shot-stopper under manager Gareth Southgate, Pickford has attracted large bouts of criticism for his over-eagerness and capacity to make mistakes during his time at the Blues.
The Telegraph says United see Pickford as a potential replacement for David de Gea.
The Spaniard's current contract expires next summer, however United have the option to extend it by a further year if they wish to do so.
But with United's wage bill reaching an eye-watering £384m last season, according to reports earlier this week, Old Trafford officials are faced with the decision on whether to hand their long-serving, £350,000 per-week-earning goalkeeper an extension or move him on to pastures new.
