The transfer window slams shut in a fortnight and the season’s opening fixtures often expose areas of weakness that managers need to address.

This transfer window has already seen both Manchester clubs splash the cash in an attempt to regain a hold over the Premier League.

Liverpool and Chelsea have also invested heavily, paying big sums for the likes of N’Golo Kante and Sadio Mane.

Manchester United have spent massively since Sir Alex Ferguson retired back in 2013 but they finally have a team primed to challenge for the title once again.

Chelsea are now at a similar stage after a season which saw them go from champions to 10th in 12 months.

Their aging squad was in desperate need of an overhaul and Roman Abramovich’s millions are set to be called upon once again.

Transfer deals often create a domino effect and one move can spark a chain of events which leads to major changes in the football landscape.

We’ve take a look at some of the big-name players who could move on as we edge towards the end of a breathless transfer window around the globe.

Kalidou Koulibaly

Napoli's player Kalidou Koulibaly

The Napoli centre-half has been one of Antonio Conte’s most sought-after players this summer after it became clear that Leonardo Bonucci was not leaving Juventus.

The Senegalese defender made 42 appearances last campaign and is seen as a long term solution to Chelsea’s ageing defence.

With Kurt Zouma still not fit Conte is keen to add to his defensive options and the Blues are said to be ready to make an improved bid for the centre-half this week.

Man City’s first game of the season saw England’s No. 1 settle for an observation role as Pep Guardiola started Willy Caballero.

News coming out of the club is that Hart is looking for pastures new as he looks to rebuild his reputation following an indifferent season with both club and country.

Everton appear likely suitors but their rival Liverpool could also pounce of the unsettled goalkeeper.

Romelu Lukaku

Everton's Belgian striker Romelu Lukaku warms up

The Belgian striker was certain to leave Goodison Park this summer but as time has gone on his protracted move away from Merseyside appears more unlikely.

After missing out on prime target Alvaro Morata, Conte has earmarked Lukaku as a possible back-up.

Lukaku is familiar with Stamford Bridge having left three years ago. He is built in a similar ilk to Chelsea’s former hero Didier Drogba and would bring both physicality and goals to Chelsea’s attack.

Riyad Mahrez

The Champions tormenter in chief could be looking for a route out of the King Power after an opening day loss that saw the Algerian looking far from interested despite his goal.

Last year’s player of the year broadcasted all his playmaking ability as he helped guide the Foxes to the most unlikely of triumphs.

But with his profile on the rise some of Europe’s top clubs are circling and Mahrez’s head could be turned with a big offer.

Alexandre Lacazette

Lyon's French forward Alexandre Lacazette celebrates

The Lyon forward scored a hat-trick on the opening day of the season while his long term admirers lost 4-3 at home to Liverpool, prompting Arsenal fans to call for the Frenchman.

The Gunners are in desperate need of a natural goal scorer and an opening day reverse may urge Arsene Wenger out of his naïve ways a splash big money on a man who can bring pace and goals – something the Emirates club is seriously lacking.

Moussa Sissoko

The Frenchman made his intentions clear after helping France to the Euro 2016 final that he was going to leave St. James’ Park in search of higher level football.

Newcastle have slapped a £30 million price tag on the midfielder’s head which may have warned off potential suitors but Sissoko has made no secret of his desire to join Real Madrid.

The Spanish giants are yet to come calling but with his pace, power and strength in the middle of the park it would be no surprise to see one of Europe’s giants make an offer he could not refuse.
