At long last, the Premier League is back.

Liverpool host newcomers Norwich City on Friday Night Football to mark the beginning of what should be another fascinating season.

Manchester City are once again favourites to win the title, but anything could happen after a hectic summer transfer window.

Most of the top six made necessary signings to improve their squads, with Arsenal spending the most in the Premier League at £150m. So much for a £45m budget.

Manchester United also splashed out, bringing in Daniel James, Aaron Wan-Bissaka and Harry Maguire for a combined £145m, while City and Tottenham spend upwards of £100m.

It was a quiet summer for Chelsea (£40m) due to their transfer ban and Liverpool, who spent barely anything.

Predicting how the top six will finish is very hard at this stage - Leicester City and Everton could even have a say - so we've taken a look at each of their best possible starting XIs.

n.b. Injuries haven't been taken into account.

ARSENAL'S BEST XI

Arsenal fans are very happy with how the transfer window went and you can hardly blame them, with Unai Emery bringing in six new players.

Nicolas Pepe should be a guaranteed starter alongside Pierre-Emerick Aubameyang and Alexandre Lacazette, while Dani Ceballos is a stronger option than Granit Xhaka in the middle.

Picking two centre-backs from Sokratis Papastathopoulos, Rob Holding and new signing David Luiz was the hardest decision, but experience could be best for now.

CHELSEA'S BEST XI

Frank Lampard has a tough season ahead of him at Chelsea after only making one signing and losing Eden Hazard and Luiz.

The biggest issue is at the back and even though Antonio Rudiger features in our strongest XI, he isn't due to return from injury until September.

Going forward, Chelsea have several strikers to choose from but none are overly convincing. Olivier Giroud is arguably the best of an average bunch.

LIVERPOOL'S BEST XI

Liverpool's best starting line-up has hardly changed from last season and that was always going to be the case considering they're champions of Europe.

One topic of debate is who should partner Virgil van Dijk at centre-back, but it's hard to look past Joel Matip after he performed so admirably in Joe Gomez's absence.

Sadio Mane, Roberto Firmino and Mohamed Salah remain dangerous as ever up top and the great thing about Liverpool's squad is they have strength in depth.

MANCHESTER CITY'S BEST XI

Can City make it three Premier League titles in a row? Judging by the above line-up, they absolutely can.

Kyle Walker should retain his place at right-back (for now) despite Joao Cancelo's arrival, while Benjamin Mendy is undoubtedly City's best option at left-back (when fit).

The only real change is Rodri in defensive midfield instead of Fernandinho, who at 34 years old can expect his game time to be reduced.

MANCHESTER UNITED'S BEST XI

United did very well to sign Maguire and Wan-Bissaka and both will be guaranteed starters in defence for 2019/20. James should arguably start ahead of Jesse Lingard out wide, too.

But there is a concern about the striking role after Romelu Lukaku joined Inter Milan and United failed to bring in a replacement.

Marcus Rashford is expected to lead the line and there are doubts about whether he's ready to shoulder the burden of being United's go-to man for goals.

TOTTENHAM'S BEST XI

Let's not beat around the bush, Tottenham have a very good team for the new season after bringing in Tanguy Ndombele and Giovani Lo Celso.

It's so good that Dele Alli will struggle to get back into the starting line-up when he returns from injury, while Lucas Moura may have to settle for a place on the bench.

Serge Aurier is a question mark at right-back and Danny Rose ought to be worried about the arrival of Ryan Sessegnon from Fulham.
