Report: Bayern Munich winger Douglas Costa on Liverpool, Barcelona radar?

Bayern Munich winger Douglas Costa has emerged as a transfer target for Barcelona and Liverpool, according to reports.

The 26-year-old joined the Bundesliga giants for £21m from Shakhtar Donetsk in July 2015 and quickly established himself as a key player under then-manager Pep Guardiola.

However, the Brazil international has struggled under Carlo Ancelotti and was left out of the starting lineup for both Champions League semi-final ties against Real Madrid in May.

According to Spanish publication Sport, Costa has been transfer-listed by Bayern, with both the Reds and the Blaugrana expressing an immediate interest in the player.

Costa, said to be valued at £30m, scored seven goals and registered nine assists from 34 games in all competitions last season.
