Earlier it has been reported that Chelsea are going after Inter Milan forward Mauro Icardi.
According to CaughtOffside, Manchester United has joined Chelsea in the race for the Serie A star.
The deal for the Argentine striker is believed to be around £99m.
It has also been reported that Icardi has been linked with a move to Real Madrid.
The 25-year-old would be an ideal replacement for Cristiano Ronaldo at the Bernabeu, with the Portugal international proving hard to replace since his summer switch to Juventus.
