New Barcelona signing Malcom hailed the stature of the La Liga champions after turning his back on an expected transfer to Roma.
The 21-year-old secured a "dream" €41 million (£36.5m/$48m) move to Camp Nou on Tuesday, just a day after Bordeaux announced they had accepted a bid from Roma.
The Serie A side are now considering their legal options after feeling as though they were forced into an "auction" despite believing negotiations were complete.
Malcom, a Brazil youth international, described his sudden switch to Barca as the fulfilment of a boyhood ambition.
