Romelu Lukaku to Inter: 40 percent; Milan Skriniar to Manchester United: 1 percent

The Belgium international recently called Antonio Conte the best manager in the world and openly expressed his desire to play in Serie A. He had previously replaced his agent Mino Raiola with Federico Pastorello, who has a strong working relationship with Inter, where a few of his clients play.

Manchester United are asking for €70 million to move Lukaku and have turned down Mauro Icardi in a potential swap -- the Nerazzurri may have to sell the Argentine striker to a third team to raise the funds. While the Red Devils could certainly use a centre-back of Skriniar's calibre, the Slovakia international recently fired his agent so he could negotiate his own extension with Inter, and Conte sees him as a key piece for his project.

Rodri to Manchester City: 70 percent

Pep Guardiola is determined to sign the Spanish midfielder to help replace Fernandinho long term, and City are among the clubs willing to pay his €70m exit clause. Rodri appears to be leaning toward joining Manchester City over Bayern Munich, and Atletico Madrid have already identified Marcos Llorente as his replacement.

Joao Felix to Atletico Madrid: 50 percent

The Portuguese wonderkid has been one of the most discussed players since breaking into Benfica's first team this season, and with the Colchoneros ready to cash in on both Rodri and Antoine Griezmann, they have the bankroll to pursue him. Benfica have made it clear that they won't accept anything but the €120m of Felix's buyout clause, while the Spanish club is looking for a way to curb the immediate outlay, possibly including a clause on future sale in order to break the impasse.

Issa Diop to Manchester United: 40 percent

Manchester United's quest for a centre-back continues, as the Red Devils have made the signing of a defender their top priority for the summer. After being scared off by the demands of Napoli and Leicester for Kalidou Koulibaly and Harry Maguire, Ole Gunnar Solskjaer's side have redirected their attention toward 22-year-old Issa Diop from West Ham, for whom they have been open to spend up to £45m. United's offer, which reportedly also included a player, was however snubbed by the Hammers, considering they are adamant they won't settle for less than £60m to let the former Toulouse centre-half leave the club.

Mario Balotelli to Parma: 15 percent

Bringing Gervinho back to Serie A last summer proved to be a stroke of genius considering he was one of the main reasons they comfortably avoided relegation, so it's not surprising to see Parma looking to double down by going after Super Mario. But at the moment, Balotelli's agent Mino Raiola is asking for a very substantial salary of €4m a season after taxes, more than double what Gervinho earns, so unless that changes, a deal is quite unlikely.

Kostas Manolas to Napoli: 50 percent

Napoli have already agreed to personal terms with Manolas and are now looking to include one player to lower his €36m exit clause, offering Amadou Diawara, who could be an intriguing addition for Roma following Daniele De Rossi's departure. Should Manolas join Carlo Ancelotti's squad, he would be expected to replace Raul Albiol, who is on his way to Villarreal, rather than Kalidou Koulibaly, who will almost certainly stay for at least one more season.

Lucas Torreira to AC Milan: 20 percent

While the Uruguayan midfielder's first season in the Premier League was a success on the pitch, Torreira has publicly stated that he has struggled to adapt to living in England. With his former manager from his time at Sampdoria Marco Giampaolo set to be appointed as Gennaro Gattuso's successor at Milan, it's not surprising to see him linked to the Rossoneri, especially considering they could use a player at his position. While Milan are trying to get some relief from UEFA with their financial fair play parameters, it's very unlikely Arsenal will let him leave considering the positive impact he had on the team.

Dennis Praet and Joachim Andersen to Arsenal: 35 percent

Speaking of Torreira, the Gunners are once again looking to Sampdoria for reinforcements. They're interested in acquiring both Belgian midfielder Praet, who has been a starter in the past three seasons, and Danish centre-back Andersen, who emerged as one of the best young players at his position during the 2018-19 campaign. The Gunners' first bid of €48m for both was turned down as Sampdoria are asking for €55m, there also could be more competition to sign the duo from Milan in the coming weeks.

David Neres to Everton: 30 percent

Following Ajax's brilliant run in the Champions League, it's not surprising to see the Brazilian international in transfer headlines. Among the keenest suitors is Everton, where coach Marco Silva would be more than happy to link up Neres with his Selecao teammate Richarlison. The £40m offer that the Liverpool-based club was preparing, however, won't be enough to sway Ajax, as the Dutch club believe that the player's value has considerably increased since January, when they already turned down a similar bid coming from China.

Mats Hummels to Borussia Dortmund: 60 percent

With the announced departures of two club legends like Franck Ribery and Arjen Robben, a new era is dawning at Bayern Munich. The rejuvenation process set in motion by the Bavarian club will affect several departments of Niko Kovac's side, including the defence, where the signings of Lucas Hernandez and Benjamin Pavard could push centre-back Mats Hummels out of the club. Borussia Dortmund -- the 30-year old's former outfit -- have already submitted a €30m offer to bring him back to the Signal Iduna Park, in a deal that could benefit both parties, considering Dortmund are looking to add more experienced players to their ranks.
