Manchester City have stuck with their boss Manuel Pellegrini after a disappointing campaign and they've backed him with the signings of two England internationals as Raheem Sterling and Fabian Delph joined the club.
They'll need more quality to beef up their defence but expect City to challenge and expect another Manchester club to join them.
Manchester United will be stronger and they've splashed the cash on exciting and quality internationals, and if Spanish shot stopper David De Gea isn't tempted by Real Madrid, they'll be a force to be reckoned with.
Arsenal signing goalkeeper Petr Cech from Chelsea makes their defence look a damn side stronger but more quality additions to their talented squad are required if they want to really challenge.
Liverpool start life without Steven Gerrard but several astute acquisitions means they will have a say but a serious title challenge is just beyond them.
2. Transfers have passed $1billion already
Clubs have spent more than $1billion dollars in this transfer window and there's still four weeks left to go.
A year ago, clubs spent £835m ($2 billion) on new players and football finance expert Rob Wilson told BBC Sport: "A new record is likely as clubs look to benefit from the new TV deal."
From the start of the 2016-17 season, the new Premier League TV rights deal increases up to £5.136 billion ($12.304 billion) and the bottom club will receive £99 million ($237 million) in prize money.
Premier League clubs will be desperate to make sure they avoid relegation to cash in on the huge sums of money that will come their way next season.
3. Star players will be fresher
There was no World Cup or European Championships in June and July following a gruelling domestic campaign. Aside from the South American contingent competing in the Copa America, most of the Premier League's finest international players have enjoyed a decent break and they'll be ready for the big kick off on Saturday.
4. Winston Reid will get better and better
The All Whites captain was linked with a move to Arsenal and Tottenham in January but he snubbed them by signing a new long term contract with West Ham in March until 2021.
At 26, Reid is at the peak of his career and while a move to a bigger club would have been exciting for New Zealand football fans, he wouldn't have been guaranteed regular first team football.
He's developed into one of the finest defenders in the Premier League and he's performed consistently for the Hammers, who look set to compete in the top half again next season.
His commitment to West Ham for the long term is the perfect opportunity for him to establish himself further at a club preparing for an exciting future.
5. The drama doesn't just happen on the pitch
It's never short of a dull moment. The characters in the Premier League are also quite capable of providing first class entertainment away from the pitch.
Arsene Wenger and Jose Mourinho's public spat in last weekend's Community Shield will spill over when Arsenal and Chelsea meet during the season. The pair love to constantly jibe one and other.
David De Gea was the best keeper in the league last season but back in 2011, he was caught stealing a bagel in a supermarket. Oops.
Sunderland fans showed support for their new boss Dick Advocaat in his first game away at West Ham - by bringing along inflatable penises to wave in the air during the match.
Providing he stays at Liverpool, who could forget about a certain Mr Mario Balotelli. The Premier League has become accustomed to his odd behaviours.
He was awful last season but he still caused a stir or two - most notably with an Instagram post of computer game character Mario, with the caption "jumps like a black man and grabs coins like a jew." Can we expect more of his bizarre antics? Hopefully yes.
