West Ham United winger Matt Jarvis admits he has already been impressed by new signing Mladen Petric.
The 32-year old Croatian striker joined the Hammers on a free this week after a spell with Fulham last season and he is already showing positive signs which could allow him to step into the vacancy left by the injured Andy Carroll.
"Mladen is a good addition to the squad," he told the club's official website.
"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."
