Arsenal fans are on a rollercoaster this season.

One match the Gunners misfire spectacularly, the next they set the field alight.

Last night, the North London club put on a vintage display, dismantling their West London neighbours West Ham with a 10-minute goal rush to savour.

German international Lukas Podolski is the embodiment of Arsenal’s seasonal schizophrenia.

Decried by the fans for being static and unhelpful a matter of days ago, the former Cologne man was scintillating against the Hammers.

And Gunners boss Arsene Wenger thinks last night’s display from Podolski and his team-mates set the tone they need to follow for the rest of the season.

"We got a good response," Wenger said. "West Ham were dangerous in the first half and from set-pieces. In the second half we created chance after chance.

"I thought it was an interesting test (at 1-0). I couldn't predict we would score five, it was vital to equalise before half-time. It was a repetition of the game at West Ham when we were 1-0 down. Everybody can score against everybody.

"I never felt that the players didn't know how important it is. I was worried they were sometimes a bit inhibited.

"Podolski was outstanding. He has an unbelievable shot, the 'keeper had no chance. It was new for us, we scored from a corner.

"I still believe (the left) is his best position. Yes, (he had one of his best games), he was also very good in the away game at West Ham."

Meanwhile, Wenger hinted that new signings are around the corner for Arsenal, to augment their push for a place in next season’s Uefa Champions League.

Asked if he had any news on transfer to report after last night’s game, Wenger said: "No. That is why I have to shorten the press conference, because I have to do some work."
