Chelsea
Antonio Conte has done well in his first few months and is unbeaten in the league with three wins out of three. The Blues were busy on deadline day as they signed two defenders, which they were trying to do since the start of August.
The return of David Luiz is a risky one, as the Brazilian is inconsistent and error prone, but the plus point in bringing him back is that he has experience of playing in the Premier League.
In:
Michy Batshuayi - £33 millionN'golo Kante - £32 millionMarcos Alonso - £23 millionDavid Luiz - £32 millionEduardo - £2 million
Out:
Mohammed Salah - £16 millionPapy Djilobodji - £8 million
Chelsea have sent 38 players on loan this season.
Grade : A -
The Blues have a strong squad that can challenge the might of both Manchester clubs, as Antonio Conte begins his revolution at the club. But Chelsea left it a little too late to sign defenders and may have overpaid for them.
Manchester United
United had another summer where the Red Devils spent more than £150 million, which included the signing Paul Pogba from Juventus, making him the world's most expensive player. It is the first time since Alan Shearer that the world's most expensive player will play in the Premier League.
The arrival of Zlatan Ibrahimovic and Paul Pogba in one window have put United on the map again.
In:
Eric Bailly - £30 millionHenrikh Mkhitaryan - £26 millionZlatan Ibrahimovic - FreePaul Pogba - £89 million
Out:
Donald Love - combined £5.5 millionPaddy Mcnair - combined £5.5 millionWill Keane - £1 millionAdnan Januzaj - LoanAndreas Perreira - Loan
Grade: A+
United have gone on and delivered their targets to Jose Mourinho. The Portuguese is building a very strong team at Old Trafford and are now one of the favorites, along with their ‘noisy neighbours’, to win the title.
Manchester City
Pep Guardiola arrived in England amidst much fanfare and has completed a major overhaul at Etihad. City have spent the most money this summer as they too crossed the £150 million mark this transfer window.
The Spaniard has stamped his authority early on by making tough decisions in his first transfer period like sending Joe Hart and Samir Nasri on loan. Claudio Bravo from Barcelona could be an inspired signing, late in the transfer window. Gabriel Jesus looks like an exciting prospect, judging his exploits at the Rio Olympics.
In:
John Stones - £47.5 millionLeroy Sane - £42 millionGabriel Jesus - £27 millionIlkay Gundogan - £22 millionClaudio Bravo - £17 millionMarlos Moreno - £4.5 millionNolito - £14 millionOleksandr Zinchenko - Undisclosed

Grade: A+
Standing toe to toe with United, Pep Guardiola has gone on to make some fantastic signings in his first season in England. In a season or two, City have the potential to go the distance in Europe too.
