Chelsea and Manchester United have held preliminary talks to try to lure Bayern Munich's Robert Lewandowski to the Premier League, Sky Sports News HQ understands.
Sky Sports' Spanish football expert Guillem Balague believes Chelsea and United have spoken to Lewandowski's representatives over a potential move.
Balague believes Lewandowski's preferred choice at this stage is Stamford Bridge, but United are thought to be very keen on landing the 28-year-old and held talks with his agent on Tuesday.
The striker signed a new contract with Bayern in December, keeping him at the club until 2021, but said recently that he was "disappointed" over a perceived lack of support at Bayern in his hunt for the Bundesliga golden boot.
He scored 30 goals last season, but missed out on the top-scorer prize to Borussia Dortmund's Pierre-Emerick Aubameyang by a single goal.
He told the Polish Super-Express: "I was not really happy with how my team helped me. I was annoyed and disappointed with the team's attitude."
And his agent Maik Barthel told German football magazine Kicker: "Robert told me that he got no support and that the coach (Carlo Ancelotti) gave no call to help him win the top-scorer title in the last game.
"He was disappointed as I have ever seen him before."
