LONDON (Reuters) - Having seen off Alex Ferguson last week, Sven-Goran Eriksson faces the second major test of his managerial reign at Manchester City on Saturday when his table-topping side visit Arsene Wenger's Arsenal.

City's hastily-assembled side lead the Premier League with a maximum nine points after an opening day win at West Ham United followed by home victories over Derby County and champions Manchester United, surprising even their most optimistic fans.

Former England coach Eriksson believes the mystery factor may now be starting to wear off.

"I think for the first two games a lot of people didn't know about some of our players, Petrov maybe, Elano and Geovanni," the Swede told the club's web-site (www.mcfc.co.uk).

"But we will not have that advantage anymore because the managers show videos about the opposition from the previous weeks. I know that Arsene Wenger will do it so I don't think we will live on surprising people anymore."

City's teenage defender Micah Richards has starred so far and was man of the match against United and England's best player in Wednesday's 2-1 friendly defeat against Germany at Wembley.

Arsenal have picked up four points from their opening two matches, a late home win over Fulham and a draw with Blackburn Rovers. In both games keeper Jens Lehmann has made costly errors. Another keeper under the spotlight is Tottenham Hotspur's Paul Robinson after his terrible blunder on Wednesday gifted Germany an equaliser.

Spurs travel to champions Manchester United, who are still looking for their first victory of the season.

However, it is Spurs manager Martin Jol who finds himself favourite to become the first top flight managerial casualty of the season.

This week the club denied they had approached Seville's Juande Ramos to replace Jol, although the speculation is unlikely to go away, especially if Spurs lose at United.

Robinson hit out at the treatment of Jol.

"We've started the season better than Manchester United, we are above them in the league, but nobody has said anything about Alex Ferguson so why should our manager be questioned?" he was quoted by the BBC as saying.

"There has been a lot that has happened and what the club has done is very disappointing."

United will still be without the suspended Cristiano Ronaldo and the injured Wayne Rooney while Tottenham will be missing top striker Dimitar Berbatov.

Second-placed Chelsea host Portsmouth while Liverpool travel to Sunderland and bottom club Bolton Wanderers hope to get their first points at home to Reading.
