Chelsea and Manchester City reportedly remain interested in trying to sign Bayern Munich defender David Alaba.
While the Austria international is regarded as a key man at the Allianz Arena, the versatile player has less than a year left on his contract.
Although Bayern are keen to keep hold of the 28-year-old, they are unlikely to be prepared to miss out on a fee for his signature.
According to The Telegraph, that has resulted in Chelsea and Man City continuing to monitor the situation ahead of a potential approach.
Given their respective issues at centre-back and left-back, the acquisition of Alaba would represent a significant coup for either of the Premier League giants.
Real Madrid, Barcelona, Inter Milan and Paris Saint-Germain have also been linked with a bid during the summer window.
