Barcelona 'were left angered' by Ousmane Dembele's refusal to join Manchester United ahead of Monday's transfer deadline - as it left them unable to buy Memphis Depay.
The French winger, 23, emerged as an alternative for Jadon Sancho as talks between United and Borussia Dortmund broke down.
Dembele was also reportedly convinced to come to Old Trafford by his international team-mate Paul Pogba.
But in the end, Dembele chose to remain at the Nou Camp and his decision scuppered Barcelona's efforts to sign primary target Depay from Lyon for £25million.
