Barcelona were interested in signing Arsenal defender William Saliba if they had failed in their bid to bring Jules Kounde to the Nou Camp, according to reports.
Saliba has become one of Arsenal's most important players since returning from his loan spell at Ligue 1 side Marseille last season.
The 21-year-old's future at the Emirates was still a talking point over the summer, with talk that he could leave the club and return to the French side on a permanent transfer.
Transfer expert Fabrizio Romano has now reported that Barcelona drew up a list of alternatives if they failed to sign Kounde - who had also been strongly linked with Chelsea.
