Matt Jarvis says the mood is confident in the West Ham United camp as they look ahead to Sunday's trip to face Southampton.

The Hammers No7 was speaking as the team finished an intensive training session at their Chadwell Heath training ground on Tuesday afternoon.

Manager Sam Allardyce took a squad including Jarvis to Spain last week to play Primera Division side RCD Espanyol, to give the players not on international duty some match action in the absence of the domestic schedule.

"It was a good game and we played a different style of team, in a big stadium with a good atmosphere. So it was definitely worthwhile and keeps everyone ticking over," he said.

"It was good to play in front of a good crowd and always good to see a strong group of our own fans there cheering us on. All in all, it was good for the lads who went over to get this time to play. Obviously training is still high tempo during this time, but it was good to have the match in the middle of it all and now we are all looking forward to the game on Sunday."

The Hammers travel to St Mary's on Sunday looking to even better the strong results they achieved against the Saints last season - it was a 1-1 draw on the south coast, with West Ham having run out 4-1 winners at the Boleyn Ground.   

But Jarvis said they know how good Southampton are on their own patch and know they need to be on top of their game to beat them.

"They are a good team and pass the ball well, but we are in confident mood. We were very disappointed in losing to Stoke in our last game, a result I think was a blip for us but something we want to get out of the system.

"We enjoyed a good point here at St Mary's last season and then beat them at home, so we know what we can do, we will go there to get a result which will see us back on track."

Jarvis said the team welcomed Mladen Petric to the training ground after he signed for the Hammers on Tuesday until the rest of the season.

He said he was looking forward to teaming up with Petric and also seeing Andy Carroll back on the pitch soon.

"Mladen is a good addition to the squad and that is what it is about, having a squad as when you have injuries and everything, others have to step up and play their part. For Andy, it is frustrating as you are working so hard to get over an injury and sometimes there are other niggles and things you pick up whilst you are doing this. Andy is a strong character and will continue to work as hard as he has been doing already to be back as soon as."
