Marcos Alonso will not join Manchester United this summer after turning down a two-year deal and intends to remain at Barcelona instead.
The 32-year-old emerged as a potential candidate to fill the void left by Luke Shaw, who suffered a muscle injury which is expected to keep him out for a number of months.
According to Spanish outlet Marca, United approached Barcelona last week to sign the defender on loan for this season.
The Red Devils offered Alonso a two-year deal, which would have seen him remain at Old Trafford after his current contract with Barcelona expires at the end of the season.
