Atletico Madrid chiefs are seriously considering a January sale for Antoine Griezmann.

The France international is enduring the worst run of form in his Atletico career and a midseason sale is now seriously being considered at the Wanda Metropolitano.

Manchester United came close to signing Griezmann in the summer and remain in pursuit, however Barcelona and Real Madrid are also keen.

The Frenchman's buyout clause is set to fall from €200m to €100m in the New Year - and transfer interest will be encouraged by Atletico leading up to Christmas.

Atletico's board feel they can afford to cash in, with Diego Costa and Vitolo to officially join the club from January 1.
