Chelsea are the Premier League's lone suitor for Bayern Munich's wantaway defender David Alaba.
Off contract in June, Alaba is prepared to be sold and leave the European champions in January.
While he has been linked with major clubs from across Europe, BILD says Alaba's agent Pini Zahavi is currently in contact with four serious suitors.
Chelsea, Barcelona, Real Madrid and Paris St. Germain are all keen on the Austria captain.
The problem for the Spanish pair, however, is that they lack the resources to meet Alaba's current €20m salary demands.
Zahavi favours placing Alaba at PSG, though the more competitive Premier League and Chelsea is favoured by the player.
