Zlatan Ibrahimovic is a reported target for Atletico Madrid.
The Swedish striker remains sidelined with a knee problem picked up towards the end of last season.
Ibrahimovic is yet to make a decision on his future with his Manchester United contract officially expiring this week.
As things stand, United are unlikely to offer the 35-year-old a new deal.
And Atleti are ready to enter the race despite their transfer ban, according to reports in Italy.
