Chelsea are reportedly locked in a battle with Barcelona, Real Madrid and Paris Saint-Germain for the signature of Bayern Munich defender David Alaba.

The Austria international's current deal at the Allianz Arena is due to expire next summer, meaning that, as it stands, he will be free to negotiate with foreign clubs at the start of 2021.

A number of clubs have been credited with an interest in the versatile defender, who remains a key player for the treble winners despite the uncertainty surrounding his future.

According to Bild, Alaba's agent Pini Zahavi has put together a four-club shortlist for his client, and La Liga giants Barca and Real Madrid are at the top of the selection.

The report claims that PSG have also been included, while Chelsea are firmly in the hunt for the 28-year-old, who has won nine Bundesliga titles during his time at Bayern.

Alaba has made 401 appearances for Der FCB, including 15 outings in all competitions this season.
