Arsène Wenger hopes Gervinho will prove to be a bargain.

The Arsenal striker made an impressive debut at Cologne on Saturday, scoring twice and looking dangerous before being forced off with a minor injury on the half-hour.

Newspapers have suggested the fee for the former Lille frontman was around £10 million, much less than many of the other strikers moving this summer. Whatever the figure, the manager feels his new acquisition is value for money.

“I hope [he’ll be a bargain],” said Wenger. “When you see all the fees around you become dizzy. We do what we want and we look first at the quality of the player and after if we have the money we spend it. In this case he wanted to join us. He had only one year on his contract so it was a good opportunity for us.”

Meanwhile, even though it was ‘only’ a pre-season friendly, the manager believes his brace on Saturday will have a positive effect as Gervinho bids to adapt.

“If, as a striker, you go six weeks without a goal you raise questions,” said Wenger. “But now it’s out of the way.

“You could see how quick he is to get behind defenders. He has qualities that are always very interesting for a team like us who have a lot of other players that go behind defenders at the right moments.”
