Petr has been on trial for the last two weeks and scored two well-taken goals against Vastra Frolunda on the Hammers recent pre-season tour of Sweden.
He told MF Dnes, “I don't know (about winning a move), it depends on the coach. I try hard,
“I would be very glad to stay. But just the fact that I am here is absolutely sensational.
“I am really satisfied with how things have gone. I think I have played three very good matches for West Ham.
“I am like in a dream and all I am missing is for the dream to come true.
“Even if it goes wrong, it will be a very big experience.
