With around a quarter of the Premier League season already gone, leaders Arsenal have successfully addressed two of the problems that hampered their title bid last season.

But Kolo Toure knows they must repeat the outstanding aspect of their previous campaign in order to banish any lingering doubts over the strength of their challenge this term.

Last season, Arsenal had an outstanding record against the top four sides but drew far too many games at Emirates Stadium and dropped a number of disappointing defeats against relegation-haunted teams.

This term, Arsenal have won all six Premier League games at home and notched victories over the current bottom three - Tottenham, Derby and Bolton. However their next two fixtures will be two of their traditional 'top four' opponents - Liverpool and Manchester United.

Toure is well aware of his side's strengths and weakness last season but that campaign has taught him not to over-estimate the importance of those occasions when the Premier League titans clash.

"Last season was a really strange season because we did really well against the big teams but we slipped up against the teams that people expect us to beat," said Toure.

"That is why this season we have to concentrate on the games in front of us - never mind if it's Liverpool or Manchester United.

"We have to keep the same focus for each game and also hope that we get a bit lucky in games and keep winning.

"The season is really long and these next two games are really important but only because we can get six points - but that's it.

"You always like to beat the teams in the top four but last season we did that and it was for nothing really because we didn't win anything.

"It's no good beating Manchester United and slipping up in other games.

"But I feel we are more mature now, we know what to expect in those games, have shown we can play against some really top players but we just need to be a bit more cautious and keep winning every game."
