Sky Sports commentator Martin Tyler says nothing can be taken for granted in a season of surprises in the Barclays Premier League.

As well as West Ham United's unforgettable 3-0 victory at Tottenham Hotspur last time out, the first seven matchdays of the new campaign have seen a number of shocks, including West Bromwich Albion's win at Manchester United and Manchester City's own slip-up at Cardiff City.

Now with the Hammers set to take on City on Saturday, Tyler is intrigued as to whether the odds can be upset once again.

"I was fascinated by the West Ham win at Spurs in the last game," he told West Ham TV. "I know all about the rivalry and how much it means for the fans to get any sort of result against Tottenham.

"To do it like that, and for West Ham to out-manouvre Tottenham tactically was a great achievement. Andre Villas-Boas is a clever manager, but all credit to Sam, the staff and the players for putting a plan into practice.

"I know there have been a couple of home defeats, which is unusual for West Ham, their strength in the home games last season was very important to where the Club finished.

"So after a good away win, the next thing you want to do is win at home and West Ham are playing a Manchester City who haven't won away.

"There are lots of imponderables going into the game, which is what makes it such a fascinating match and why I'm delighted to be commentating on it."

Tyler has not commentated on a match at West Ham's home ground since a 2-2 draw with Arsenal in 2009, and he hopes this match will provide just as much drama.

"I'm looking forward to the game enormously," he continued. "I look forward to every game, but this will be the first time I've done a West Ham game at the Boleyn Ground for four years, I think. That was a great game, with West Ham coming from two-down to draw 2-2 with Arsenal.

"I don't get to choose my games, my bosses do that for me and it's just complete coincidence [that it has been so long].

"I have fantastic memories of West Ham - in my playing days I was in the same team as Ron Greenwood's son, so long before I was a journalist I'd get all sort of titbits about what was going on here.

"So at the end of a week where England have qualified for the World Cup, to come to the Club which won the World Cup for England, as all West Ham fans know, it also feels appropriate."
