And then along comes Sergio Aguero. Two goals and an assist in a blistering 30-minute spell has pretty much everyone who follows the Premier League talking about it today, including the man himself who tweeted a rather encouraging sign that there is plenty more to come.

: "Very happy with my debut for City. Hopefully the start of something big. Thank you to my team-mates and the fans for their support."

Although Aguero's  debut in

was very impressive, comparing it to other footballers making their mark in the Premier League will be a good gauge of what to expect from the Argentinian, who might just be what City needed to challenge to Man United for the title this season.

1. Jurgen Klinsmann

Sheffield Wednesday 3-4, Tottenham Hotspur August 20, 1994

The German arrived in London with the reputation as someone who liked a dive. So his celebration after both goals in his debut in English football, when he dived on the ground, showed his sense of humour was as keen as his finishing skills.

He went on to score 21 league goals was Player of the Year.

2. Fabrizio Ravanelli

Middlesbrough 3-3 Liverpool, August 17, 1996

You can't really get any better than scoring a hat-trick on your debut - and at home against Liverpool as well.

The Italian White Feather built on this start with 17 league goals, which wasn't enough to save Boro from relegation. They also lost both cup finals.

3. Michael Owen

Wimbledon 2-1 Liverpool, May 6, 1997

Every Liverpool fan had heard about the kid in the reserves who was a flying machine with an eye for goal. So at the tail end of the season, a 17-year-old Owen was given his long-awaited chance.

Liverpool may have lost this game, but the way he sped through Wimbledon's defence and calmly finished was a sign of things to come.

4. Alan Smith

Liverpool 1-3 Leeds United, November 14, 1998

It's pretty decent to score on your debut, but to do it with your very first touch in senior football is something special.

Smith had just turned 17 when he was put on as a second-half substitute at Anfield. He read a pass from Jimmy Floyd Hasslebank, ran through on goal and finished like a veteran. One touch, one goal.

5. Cristiano Ronaldo

Manchester United 4-0 Bolton Wanderers, August 16, 2003

No goal, but plenty of skill from a Portuguese teenager who was on his way to becoming the world's best player.

United fans may have been unsure whether this new kid was good enough to take over David Beckham's No7 jersey. He soon proved he was and then some.

Bolton had no idea who to cope with his skill, pace and vision.
