West Brom boss Tony Mowbray is unsure what sort of impact new Dutch signing Gianni Zuiverloon will make after committing himself to his country's Olympics campaign.

"We will look at him when he comes back, see how much football he has played and see how he feels mentally and physically," Mowbray told the Birmingham Mail.

"But that's my job and I assess players all the time to decide whether they are mentally and physically ready.

"When Gianni gets back to our training ground I will have a look at him and decide what I think."
