You may feel like you've only just stopped watching football due to the World Cup gracing our screens throughout the summer, but we aren't that far away from welcoming the beautiful game back to our screens.

The Premier League returns in just over a fortnight’s time, and a lot has changed since the end of last season.

Arsene Wenger has finally left Arsenal. Antonio Conte has been sacked by Chelsea. Liverpool have spent big, and Jose Mourinho hasn't stopped moaning.

It's truly been a bonkers summer, and with the action set to start soon, it's time to look into the Premier League's 'big six'.

Here, Press Association Sport have taken a look at how the ‘big six’ are preparing for the campaign.

Arsenal

It is a new era at the Emirates Stadium with Unai Emery replacing the long-serving Arsene Wenger at the helm and immediately starting to reshape the squad.

The arrivals of Stephan Lichtsteiner, Bernd Leno, Sokratis Papastathopoulos, Matteo Guendouzi and Lucas Torreira will give the Gunners a fresher look in defence and midfield.

Jack Wilshere, once tipped to become the face of Arsenal, has moved on after being robbed of momentum by injuries, while Santi Cazorla and Per Mertesacker have also left, with the latter joining the coaching team.

With World Cup players Mesut Ozil, Alex Iwobi and Mohamed Elneny returning ahead of the summer trip to Singapore, Emery now has close to his full squad to work with.

Emery’s revamp is not finished yet, however, with more defensive and midfield recruits possible. Caglar Soyuncu, Steven Nzonzi and Ever Banega have all been linked.

Eyes will be on how Ozil performs in the early part of the season. The German was heavily criticised last season and then endured a troubled World Cup, culminating in a controversial decision to retire from international football.

Chelsea

A new manager arrives at Stamford Bridge in Maurizio Sarri, bringing defensive midfielder Jorginho with him from Napoli.

Sarri is yet to get to work on his squad, with no major departures yet.

Sarri’s pre-season preparations may have been hampered by the absence of numerous first-teamers for their pre-season tour of Australia due to the World Cup. Those missing include both goalkeepers Thibaut Courtois and Willy Caballero, as well as Victor Moses, Cesar Azpilicueta, Gary Cahill, N’Golo Kante, Eden Hazard, Olivier Giroud and Willian.

With the changeover from Antonio Conte to Sarri occurring relatively late in the summer, the Blues may be a little behind in their preparations.

Sarri will also have to address the uncertainty over the futures of Hazard and Courtois.

Liverpool

Jurgen Klopp has been busy, determined to prove last season’s run to the Champions League final was no flash in the pan.

The £65million signing of Alisson – a world record for a goalkeeper – addresses a longstanding issue. Fabinho, Naby Keita and Xherdan Shaqiri also add depth and quality.

Midfielder Emre Can is the most senior departure, although goalkeeper Danny Ward has sought a fresh challenge at Leicester.

Sadio Mane and Mohamed Salah returned to training ahead of this summer’s tour of the United States, but Jordan Henderson, Trent Alexander-Arnold, Roberto Firmino and Simon Mignolet are still taking time off.

Danny Ings has a minor injury, but Alex Oxlade-Chamberlain could miss the whole season.

Klopp appears to have completed his summer business. It is now down to him to incorporate the new players into his exciting squad and try to build on last season’s promise.

Manchester City

The Premier League champions are not resting on their laurels having paid a club record £60million for forward Riyad Mahrez.

Yaya Toure’s depature at the end of last season ended one of the great City careers, although he had become a peripheral figure. There has been no other trimming of the first-team group.

City travelled to the US for their pre-season tour without a host of players. Of the 16 involved in the World Cup, only Benjamin Mendy and Bernardo Silva were involved.

City were disappointed to lose out on Jorginho to Chelsea having made a defensive midfielder a priority, but they are not certain to look for another player in the position.

In truth, after winning the title with a record 100 points, there are few weaknesses in Pep Guardiola’s compelling squad.

Manchester United

Jose Mourinho has bolstered his midfield with the signing of Brazil midfielder Fred, while youngster Diogo Dalot adds a defensive option.

Michael Carrick has joined the coaching staff after hanging up his boots, while Daley Blind has returned to Ajax.

United have been without a host of stars for their pre-season tour of the US, including Romelu Lukaku, Paul Pogba, Marouane Fellaini, Marcus Rashford, Ashley Young and Jesse Lingard, while David de Gea and Fred have arrived late.

It has been a curious summer for United, with fewer signings than expected so far and the only other major business being a new contract deal for Fellaini.

Mourinho appears to have been playing down United’s prospects while rumours persist that his relationship with Pogba is troubled.

There is uncertainty over the future of Anthony Martial.

Tottenham Hotspur

Spurs have not yet made a signing this summer, although they will be very happy to have tied key players Harry Kane and Son Heung-min, as well as manager Mauricio Pochettino, to new long-term contracts.

There have been no major departures from White Hart Lane.

Spurs did have Christian Eriksen, Davinson Sanchez and Son back for their pre-season friendlies in the US, but, like most top teams, were still without a number of first-team regulars.

These included Kane, Kieran Trippier, Dele Alli, Eric Dier, Hugo Lloris, Toby Alderweireld, Jan Vertonghen and Mousa Dembele.

It has been a quiet summer for Spurs, but Pochettino does not seem unduly concerned by the lack of transfer activity.

When they do finally dip into the market, centre-backs and wingers could be on their shopping list.

The long-term future of Danny Rose also remains uncertain.
