Both Manchester clubs could be set for a battle for the signature of Barcelona star Sergio Busquets as contract talks with the Catalans remain ongoing.
The 26 year-old, who has 74 international caps with Spain, made his first-team debut in 2008 after progressing through the famed academy, has been the subject of speculation as the club tries to tie down the defensive midfielder on a long-term contract.
He has little over a year left on his current contract and is keen to improve on his current deal believed to be worth €85,000 a week.
Busquets has been a first-team regular under Luis Enrique, but has been under more scrutiny this term with the new set-up leaving the player exposed on occasions with full-backs Jordi Alba and Dani Alves have pushed further up the pitch to supply width.
With Ivan Rakitic and Xavi covering the pair at times, Busquets has been left exposed on a number of occasions in front of the defence and a number of Premier League clubs are paying close attention to his situation.
City and United have shown interest, while The Star reports that Chelsea and Arsenal would also be keen to bring the midfielder to England. The Blues were heavily linked to the Spaniard before Christmas, though Nemaja Matic has been in sparkling form all season in the same position.
Busquets has made 308 appearances for the Catalans and scored 12 goals since his debut.
Chelsea are monitoring the situation of Liverpool forward Raheem Sterling, after the England international turned down the Reds' latest contract offer, according to the Daily Express.
