#3 Hector Bellerin | Arsenal to Barcelona

In a shocking twist, Barcelona are said to be looking to offload Brazilian full-back Emerson Royale in the coming hours, with Arsenal's Hector Bellerin being lined up as a potential replacement for the former Real Betis defender.
Emerson is yet to play a full game following his switch to Camp Nou this summer. Tottenham Hotspur have shown interest in signing the Brazilian and they've allegedly submitted a bid worth €30 million to secure his services. Barcelona are open to a transfer as they look to raise some cash amid their financial crisis.
Meanwhile, Bellerin is believed to have reached the end of the road at the Emirates Stadium and is said to be looking for a way out. Barcelona are eyeing a swoop for the Spaniard if they end up selling Emerson in the coming hours.
#2 Ruben Neves | Wolves to Manchester United

After strengthening the defense and the attack by signing the likes of Raphael Varane, Jadon Sancho and Cristiano Ronaldo this summer, Manchester United have now prioritized the signing of a defensive midfielder before the end of the transfer window.
They've been heavily linked with Wolves star Ruben Neves over the last couple of hours and it appears a breakthrough could be reached very soon.
The Portuguese has a market value of around €45 million, as per Transfermarkt, but that could be lowered slightly in negotiations. It remains to be seen how things will pan out before the transfer deadline tomorrow.
#1 Kylian Mbappe | Paris Saint-Germain to Real Madrid

In what could be the biggest transfer on deadline day, Real Madrid are well-poised to lure Paris Saint-Germain attacker Kylian Mbappe to the Santiago Bernabeu. The Frenchman has made it clear he wants to move to the Spanish capital and with less than 11 months left on his contract, the Ligue 1 giants could decide to cash in on him.
According to reports, Los Blancos have submitted a gargantuan €215 million bid to sign the winger. The Parisians are said to be considering the bid, having earlier turned down an offer of about €160 million from the La Liga giants.
As it stands, Mbappe is in advanced talks to join Real Madrid and the deal could well be completed in the coming hours. Should the transfer go through, the attacker will reportedly pocket about €35 million net per annum, which would make him the highest-paid player at the Santiago Bernabeu.
