Chelsea's top scouts watched Sheffield United defender Harry Maguire in action against Fulham last night, according to the Metro.
Maguire was linked with a move to Manchester United in September as Sir Alex Ferguson had reportedly identified the 20-year-old as a potential long-term replacement to both Rio Ferdinand and Nemanja Vidic.
However new Manchester United boss Moyes did not follow up Ferguson's initial interest in the centre-back as he was focused on his search for a new midfielder.
And it now appears Manchester United could lose out to Chelsea in the race to sign the England Under-21 starlet.
Chelsea boss Jose Mourinho is keen to strengthen his defensive options at the end of the season as the Blues are still heavily reliant on John Terry.
