The 31-year-old’s current contract at Turf Moor is set to expire at the end of the month as Burnley have decided against offering the versatile star a new deal to remain with the Clarets.
Caixinha has already made five signings this summer and is expected to add to that, bringing in Bruno Alves, Ryan Jack, Dalcio, Fabio Cardoso and Daniel Candeias.
With a large chunk of the Portuguese manager’s transfer budget already spent, a free signing that can still improve the squad is likely to be favoured by Caixinha and that could come in the form of Boyd.
