Real Madrid have put rumoured Manchester United target Toni Kroos up for sale for £50m, according to a report.
The Red Devils came close to signing the Germany international in 2013, only for Real to hijack the transfer at the last moment.
United have remained interested in Kroos ever since, however, and The Sun suggests that they may make a fresh approach for him this summer.
Unlike in previous transfer windows, it is claimed that Real are more open to doing business this time around as the 29-year-old's stock has fallen following a poor campaign for club and country.
Three-times Champions League winner Kroos is under contract until 2022, but he is believed to be seeking a move away to reignite his career and has previously admitted to being interested in a switch to the Premier League.
Paris Saint-Germain and Manchester City may also be in the running to sign Kroos.
