It would not have been bad for Barcelona at all had PSG signed Emerson, but it seems like their interest was nothing more than just a rumour. The Brazilian's time at Betis is coming to an end and that could be a problem for Barcelona.
Emerson's situation is unusual. He is owned by both Betis and Barca. It was agreed that he would spend two seasons at the Andalusian outfit and then move to the Catalans.
But in that time, Barcelona have reinforced their right side of defence with the signing of Sergino Dest and the progression of Mingueza. That means that Emerson does not have place at Barca right now.
According to 'Mundo Deportivo', PSG's interest in the player in the last few hours of the transfer market was in vain. The French club have no intention of going for the Brazilian full-back in summer which is when Emerson is set to move to Barcelona.
