The report adds that Chelsea are open to selling the 24-year-old, who scored 10 goals in the Premier League last season, but could demand a transfer fee of £80m. That figure would represent a significant profit for Chelsea as they spent £32m on signing Jackson from La Liga side Villarreal two years ago.

The 24-year-old would tick a lot of boxes for potential suitors, though he would not come cheap. Jackson's pace and work-rate make him a real threat on the counter-attack and he repeatedly stretches defences with runs in behind.
