The summer transfer window officially swings open on July 1st, but the negotiations and confirmations have already begun.
Asmir Begovic, Pablo Zabaleta and Bernardo Silva are three players who have all already opted for new surroundings ahead of the new season.
With May barely gone, the transfers are only going to come thicker and quicker before the August 31st deadline.
Here, we take a look at five transfers that could seriously shake the footballing world.
The French wonder-kid has been the single biggest breakthrough young player this season.
Champions League semi finalists AS Monaco will be fighting off suitors after the teenager’s signature.
Having been linked with basically every top European club, whoever captures this forward will have a decade of future quality in their ranks.
With 26 goals in 44 games this term, scoring a goal every 101 minutes, Mbappe has all the potential to become a top forward in world football.
Whoever captures this lads signature has possibly signed themselves a forward for the next 15 years.
Heavily linked with Manchester United for a long time, this transfer seems likely to be finalised over the summer.
Should Griezmann swap Madrid for Manchester, he could provide United with the fluid, creative spark they lack.
Jose Mourinho’s side struggled to a sixth place finish in the Premier League, finding it difficult to win games against so-called lesser teams.
The Frenchman could be seen as the player to break down compact, defensive sides with his intelligent movement, quick movement and goal-scoring knack.
With the future of Zlatan Ibrahimovic, Utd’s top scorer last season, still unclear, it could be a no brainer for Mourinho to sign the Atletico forward.
A reported £100 million pound release clause is a steep fee, but the Old Trafford side aren’t afraid to spend big on one player, signing Pogba last summer for almost £90 million from Juventus.
The Chilean will be a coup for a club should he decide to quit Arsenal, but will leave the Gunners in deep trouble.
He’s been Arsene Wenger’s star man, and is easily the best player at the Emirates.
Arsenal’s habit of letting player contracts run down to the skin-of-their-teeth is a concern for many of their supporters, and they could lose another key player through it.
His goals, 30 in all competitions, helped the North London side to another FA Cup win, but only a fifth place finish.
No Champions League football could be his excuse for heading elsewhere.
There will be an abundance of managers after Sanchez, with Sevilla rumoured to be leading the pack.
Virgil Van Dijk
Southampton’s Dutch centre half impressed many people before injury halted his season in January.
Rumoured to be joining Liverpool in this window, a central defensive pairing of the 25-year-old alongside Joel Matip is an exciting prospect.
The former Celtic and Ajax man is reportedly expected to cost £50 million.
Manchester City, Arsenal and Chelsea are also interested in the tall defender, but rumours say he wants to play for Jurgen Klopp.
Liverpool’s frail defence would be significantly improved with Van Dijk, and if he moves to Anfield, it could prove to be a major improvement for Klopp’s side.
Everton’s star man can’t decide whether he wants to stay or leave Merseyside this summer.
In March, he publicly stated he wanted to leave to win more trophies, something the Blues haven’t done since 1995.
Everton boss Ronald Koeman has since told the press he expects Lukaku to stay at Goodison Park next season.
Chelsea are believed to be interested in re-signing the Belgian forward who scored 26 goals for the Toffees this term.
He does have two years remaining on his contract, however, his agent is believed to be manoeuvring for improved terms.
Antonio Conte could swoop for Lukaku if Diego Costa decides to leave Stamford Bridge, and a Chelsea reunion may be too tempting for Everton’s number 10.
