It's transfer deadline day across Europe's top leagues, and the big question on everyone's mind is: will Neymar return to Barcelona? The Brazilian has been linked with a move back to Camp Nou throughout the summer, <a href="https://www.thenational.ae/sport/football/neymar-set-to-stay-at-psg-after-return-to-barcelona-falls-through-reports-1.905056">though reports in France on Sunday</a> said the forward would remain at Paris Saint-Germain this season after failing to force a move. Neymar, 27, became the world's most expensive player when PSG paid €222 million (Dh897m) for his transfer from Barcelona two years ago. But with some time still to go before the transfer window closes, don't expect to have heard the last of this story. There has already been significant movement across Europe with several big-name moves over the past 48 hours. Colombian striker Radamel Falcao was greeted by 25,000 Galatasaray fans, according to local media, after signing for the Turkish giants from French club Monaco. Henrikh Mkhitaryan arrived in Italy on Monday ahead of agreeing a season-long loan to Roma from English club Arsenal. Napoli signed Spain striker Fernando Llorente, who left Tottenham at the end of last season while Javier Hernandez has joined Spanish club Sevilla from West Ham United for a fee of £7.24 million (Dh32 million).
