Mikolanda has been impressive during his pre-season netting twice against Vastra Frolunda and once in the 2-2 draw against Yeovil Town.
Petr, a Czech U-21 international, is looking forward to the challenge of breaking into the first team and trying to fire the goals that may or may not keep the Hammers in the top flight this season.
He told the official site, “I am very happy to have signed at West Ham United.
”Teddy Sheringham was my hero when I was growing up. I remember watching his goal against Bayern Munich in the Champions League Final.
”I never dreamed that I would meet him, let alone be training alongside him. It's a fairytale.”
