Manchester United and Chelsea have both expressed interest in signing the Paris Saint-Germain defender Marquinhos who is valued at around 50million euros (£40million) by the French champions who would, however, prefer to negotiate a swap deal if they decided to sell this summer.

PSG do not want to part with the Brazilian international – who turns 22 next month - but are aware that other clubs are circling and that he may be unsettled. Barcelona are also considering whether to make a bid for Marquinhos.
