Chelsea's defensive pair Cesar Azpilicueta and Marcos Alonso are both keen on a move to Barcelona this summer, according to reports in Spain - in a move that see Thomas Tuchel needing almost an entirely new back line.
The Spanish duo have been mainstays at Stamford Bridge - with Alonso joining in 2016 while captain Azpilicueta has been on their books since the 2012-13 season.
Azpilicueta came close to leaving Chelsea on a free transfer this summer before penning a new one-year extension, while left-back Alonso's deal will finish at the end of next season.
