West Ham United have signed Czech Republic right-back Vladimir Coufal from Slavia Prague for £5.4m.
Coufal, who has eight international caps, has arrived at the Premier League club on a three-year contract, with the option of a further two.
"I knew about the interest West Ham had in me for a long time but now finally I am here and I am so happy," said Coufal, 28.
He follows compatriot Tomas Soucek to the Hammers from the Czech champions.
West Ham manager David Moyes said Coufal is "the type of player we want - hungry, ambitious and determined".
