Lucas Torreira, Arsenal: Hands up who had never heard of Torreira before his £26.4m move from Sampdoria. Everyone has heard of him now. Small in stature but bites hard, passes, scores and has added an extra vibe at times which has been missing from Arsenal's midfield for some time. Reuters
David Brooks, Bournemouth: There aren't many players that come from the lower divisions and take to the Premier League like a duck to water - especially aged just 21. The Welsh international wideman cost £11.5m from Sheffield United and has fitted straight into Bournemouth's fluent style, adding five goals including both against Brighton at the weekend. A bright future lies ahead and a sharp increase in his transfer value. Getty Images
Richarlison, Everton: Eyebrows were raised when £40m was forked out for the Brazilian after a single reasonable season at Watford. But he sprung into action with two goals on his debut and another in his second match for Everton. He now has eight, plus three more for Brazil this season and has become the focal point of his club's attack. Again, not bad for a 21-year-old whose best years are ahead of him.

Riyad Mahrez, Manchester City: The critics questioned whether he would be swallowed up at City and find himself warming the bench for long periods behind Raheem Sterling and Leroy Sane. While he hasn't started every game, he has however made a significant impact, scoring seven times since his £60m move. He's shown there was life beyond Leicester City and his double act with Jamie Vardy. He's at the right club and has fitted in wonderfully. Reuters
Xherdan Shaqiri, Liverpool: You wonder how many clubs were put off by the Swiss' apparent sulkiness during Stoke's relegation campaign last season. Liverpool took the plunge and their £13m looks a snip. Like Mahrez, it was tricky to see where he would fit in with the form of Salah, Mane and Firmino, but he's taken his chances when they've come with five goals and is versatile enough to play in midfield or attack. Could end up being the bargain of the season. Reuters
