Mladen Petric feels he is nearing full fitness after coming through 90 minutes in Thursday's behind-closed-doors friendly at the Boleyn Ground.

The Croatian was on the score sheet as an experimental Hammers side went down 4-2 to Chris Powell's Charlton Athletic.

A towering header from a Matt Jarvis cross brought the Croat his goal in a hard-working display and Petric insists he is improving with every passing day.

He told West Ham TV: "It was a good day, I played 90 minutes after a long time which was very good for me and of course I'm glad to score a goal but it's only a friendly, so it doesn't count for too much.

"It was good, not just for my fitness, but some other players as well and it was very important to get 90 minutes. I feel better and better each day and I don't think it's long before I will feel 100 per cent fit."

It has been just over a month since Petric put pen to paper on a deal which will see him at the club until the end of the 2013/14 season. And while the frontman is yet to start a competitive clash for the Club, he reckons he is fast reaching the same levels of fitness as his teammates.

"My fitness is much better than when I started three weeks ago. I saw how big the difference was between me and the other players and now I feel like every day that difference is getting smaller and smaller."

While Petric has, to date, been limited to three substitute appearances for the Hammers, he feels he has settled in well among Sam Allardyce's squad.

He said of the team: "It's been nice, they're all very kind, very good lads and every day I've been enjoying it. I get on well with everybody, of course I get on well with Guy [Demel], because I know him from Hamburg and Raphael Spiegel, because he's from Switzerland and we speak the same language. "

The striker was a delighted onlooker in the team's last Barclays Premier League fixture, as the Hammers employed a formation without a recognised striker against Tottenham Hotspur.

Big Sam's tactics proved a big hit as the visitors ran out 3-0 winners and the striker was happy to see the team win, although admitting he is itching to play.

"It was a very important win for us and it was a much, much better atmosphere around the place. You could see that everyone's been laughing and having fun in training, which has been nice.

"The last couple of weeks hadn't been very good for us, because of the results, and I'm sure they'll make some more jokes when we win some more games!

"I hope to be involved but it's the manager who decides and we will see. I didn't play against Tottenham but we won the game and that's the most important thing.

"I think it was a big surprise for Tottenham, which is why we played so well and, of course, it is a good option to have for some games. On the other side of that I'm a striker, I want to play and I'm sure I'll get my time on the pitch."
