The Premier League is now playing host to football's best managers.
The likes of Arsene Wenger, Jurgen Klopp, Pep Guardiola, Jose Mourinho, and Antonio Conte will all be vying for the Premier League title next season, along with the likes of Claudio Ranieri and Mauricio Pochettino.
With big names, comes big reputations,nd because of those reputations, star names have been lured to the Premier League already in this summer's transfer window.

However, just because they come with a reputation, and sometimes a hefty price tag, that doesn't mean they will automatically succeed.

Here are key reasons why five big summer transfers could fail to impress in the Premier League.
Zlatan Ibrahimovic may have been considered some kind of God in Paris, but he will need to produce something the Premier League has never seen before in order to gain the same title in Manchester.
The 'Swedish King' recently completed his free transfer to Old Trafford after ending his four-year spell with Paris Saint-Germain, which saw him score an impressive 113 goals in 122 games.
As impressive as that does sound, the majority of his 113 goals were netted during Ligue 1 games, possibly the least challenging league in the whole of Europe. He may have endured successful stints with other major clubs like Barcelona and both Milan clubs, but that was a few years ago, and the striker isn’t getting any younger.
An out-and-out striker is undoubtedly what United needed, but Ibrahimovic hasn't quite had a challenge as tough as the Premier League.
So at the tender age of 34, it will be difficult for United's new star to set the league alight like he has on so many occasions in the past.
As well as new teammate Zlatan Ibrahimovic, Eric Bailly recently completed his summer transfer to Manchester United, after the club forked out £30 million for the central defender.
Bailly only spent a year at previous club Villarreal, who paid just £5.7m for his services.
A lot will be expected of the 22-year-old, especially signing for one of the biggest clubs in the world, who have produced some of the best central defenders the Premier League has ever seen.
He will have to prove his worth against players like Diego Costa, Sergio Aguero, Harry Kane, and Romelu Lukaku in his debut season, and at the age of just 22, it’s going to be a very difficult task for the young prospect.
Pep Guardiola’s first signing as City boss was former Borussia Dormund midfielder Ilkay Gundogan.
The German midfielder was once regarded as one of the best young prospects in Europe, winning both the Bundesliga and DFB-Pokal in the 2011-12 season. Since then, however, he suffered a major injury in August 2013 which he never really recovered from. It also meant that he only managed to make one appearance during the 2013-14 season.
He managed to play a combined 48 games over the past two campaigns, but another knee injury saw him miss Euro 2016 with Germany.
With the likes of Fernando, Fernandinho, and Yaya Toure in the way, Gundogan may find it increasingly difficult to secure a place in Guardiola’s staring XI.
Arsene Wenger and the Arsenal authorities once again put their hands in their pockets to bring another expensive midfielder to the Emirates Stadium.
This transfer follows the £42 million signing of Mesut Ozil in 2013, and Alexis Sanchez in 2014 for the fee of around £35 million.
Both proved very successful signings for Wenger, but 23-year-old Granit Xhaka will need to have an outstanding first season with the Gunners to follow in their footsteps.
Arsenal made Xhaka their third most expensive signing ever with a fee in the region of £30 million, but the Swiss midfielder will have to replace the likes of Santi Cazorla, Aaron Ramsey, Mohamed Elneny, Jack Wilshere, and Francis Coquelin in order to justify his hefty price tag.
Along with Zlatan Ibrahimovic, Batshuayi will be making the short journey across the English Channel.
The Belgian forward turned down a move to London rivals: Tottenham Hotspur, West Ham United, and Crystal Palace in favour of a move to Chelsea.
The Blues forked out around £33.5 million for the striker after Diego Costa expressed his doubts about his future and Antonio Conte’s desire to deploy the 3-5-2 formation.
The Belgian forward struggled for game time during his country’s shock exit at Euro 2016, and could only manage 17 Ligue 1 goals in 36 games.
It seems like a good enough record for a striker of his age, but in a league that is nowhere near the standard of the Premier League, you would expect a much more efficient goal-to-game ratio, which is what he will find very difficult to do in the upcoming season.
