Chelsea are hopeful of securing Fiorentina's Marcos Alonso before the transfer window shuts on Wednesday.
Antonio Conte has earmarked the 25-year-old as someone who can help balance his back four, with Alonso looking likely to cost £23million.
Here, Sportsmail takes a look at a player who has spent time in England before with varying degrees of success.
Is this is the guy from Bolton?
Yes, the very same. Alonso moved to Wanderers in 2010 - still a Premier League team then - and spent much of his first two years there playing for the Under 21s at the Lancashire FA's base in nearby Leyland.
