With the dust settling on a record-breaking summer transfer window, all 20 Premier League clubs will be hoping their investments pay off in the weeks and months to come.
Reflecting on the business that's been done, tactics analyst Adrian Clarke picks out five signings that are likely to transform the way their new team perform.
He kicks off the series with a look at a key addition to the Arsenal squad.
Granit Xhaka
Granit Xhaka has the potential to transform Arsenal's midfield this season. Blessed with a delightful mix of defensive, physical and creative qualities he can be the dominant all-round engine-room presence the side has been crying out for.
There are many strings to his bow but the Switzerland international's impressive range of passing stands out as being exceptional.
Capable of hitting an inch-perfect cross-field or forward passes, the Gunners now have somebody with the speed of thought and accuracy to stretch opposition sides in a flash.
This wasn't evident last term when they produced the fewest long balls per match of anyone (49) in the Premier League. Their quicker attacking players such as Lucas Perez, Theo Walcott, Alex Oxlade-Chamberlain and Alexis Sanchez are sure to be beneficiaries when he looks to find them with passes lofted in behind.
Prior to his first couple of Premier League starts there were mild concerns over Xhaka's mobility and defensive nous - especially in comparison to the hardworking Francis Coquelin - but those doubts have been firmly dispelled.
To date he has an almost identical record in terms of breaking up play; he has comprehensively outran the Frenchman and been substantially more involved in general build-up play.

By offering just as much to the team with and without the ball, Arsene Wenger now has two players rolled into one with Xhaka, effectively meaning he can field an extra attack-minded creator.
His deep-lying double-pivot combination with Santi Cazorla worked wonderfully well at Watford last weekend. Together they exerted full control of the midfield with calm and combined assurance in possession. Stronger opponents will test their credentials as a pairing but Xhaka's arrival has immediately improved a key area of the pitch.
