Wenger issues serious warning to Gunners

Arsene Wenger believes beating the Premier League strugglers will be key to Arsenal's chances of mounting a serious title challenge this season.

The league leaders host bottom-of-the-table Derby at the Emirates Stadium tomorrow - the Rams have yet to score and lost their last away game 6-0 at Liverpool.

However Wenger has warned against complacency - his team failed to produce the

goods in similar matches last season.

"It is a big game, because last season we dropped points against these

teams," he said.

"This year we want to take points against these teams and this year we have

achieved that up to now.

"We want to keep our home strengths and it is a weekend where we can stay in

the position where we are in.

"We do not want to damage that position because you do not have completely the

right focus.

"It was only two months ago that people were saying we had no chance of finishing in the top four.

"I had a massive belief in them, but how far they go is down to us. That is

the challenge we have in front of us.

"The belief has been strengthened but we have not won anything.

"It is all to do. I have the belief we have the potential to win, but it is

all to do."

The Arsenal manager is set to "rotate a little bit" tomorrow, with Gilberto,

England Under-21 forward Theo Walcott and Croatian striker Eduardo - on target

in midweek - all in contention to start against the Rams.
