Premier League giants Manchester United are interested in Real Sociedad winger Takefusa Kubo.

The Japanese international, who is at the Asia Cup, has a release clause of £51 million.

Per Mundo Deportivo, Kubo is emerging as a possible attacking option for United in the summer.

The Red Devils are not planning any spending in the winter transfer window this January.

Liverpool, Juventus and Saudi side Al-Nassr are the other teams chasing after Kubo.

However, the Japanese star is happy at La Real and the club will try to convince him to stay.
