Burnley and Netherlands striker Wout Weghorst has emerged as a surprise loan target for Manchester United.
Weghorst is currently on loan at Besiktas in Turkey, where he has scored eight goals in 16 appearances.
The 30-year-old's latest came in a 2-1 win against Kasimpasa on Saturday, after which he appeared to wave goodbye to Besiktas' fans.
It is understood there is no break clause in the loan from Burnley, so talks would involve all three clubs.
Erik ten Hag has made no secret of his desire to bring in striking reinforcements following the departure of Cristiano Ronaldo.
