#3 Jules Kounde to Chelsea
Chelsea have sold Kurt Zouma to West Ham United for £31.5 million, which means they have room for the arrival of centre-back Jules Kounde from Sevilla.
Kounde is regarded as one of the best young centre-backs in the world, and was close to joining Manchester City last summer, who instead signed Ruben Dias. The France international has impressed with his performances for Sevilla, and Chelsea have been heavily linked with him for some time now.
With Thiago Silva and Cesar Azpilicueta both in their 30s, and Antonio Rudiger 28, it is clear Chelsea are planning for the future. The 22-year-old Kounde could prove to be an excellent acquisition, but it remains to be seen whether the Blues can sign him this summer.
#2 Manchester City's hunt for a striker
Manchester City entered the market wanting to sign a striker, but they are yet to do so.
They have splurged nearly £106 million to sign Jack Grealish from Aston Villa. While Grealish is definitely a sensational signing, he doesn't address a problem area for Manchester City. They lacked a prolific goalscorer last season, and it looks like that could be the case this season as well.
Harry Kane was their primary transfer target. but the striker has admitted that he intends to stay with Tottenham Hotspur this summer. Cristiano Ronaldo was heavily linked with City, but he is now on his way to Manchester United. Fiorentina's Dusan Vlahovic has been suggested as a possible option for Manchester City.
#1 Kylian Mbappe to Real Madrid
Two global superstars have already changed clubs this summer, and Kylian Mbappe could follow suit soon.
PSG signing Lionel Messi has been suggested as a possible reason for Mbappe wanting to leave the club. The France international has been perennially linked with a move to Real Madrid. So if he doesn't go to Spain this summer, it is very likely he will join Madrid next summer when his contract with PSG expires.
Real Madrid have reportedly had a €160 million bid for the superstar forward rejected by the Ligue 1 giants. The 22-year-old is extremely keen on a move to Los Blancos, but it remains to be seen if Paris Saint-Germain let Mbappe leave this summer.
