The former England under-21 striker slipped through Stoke's fingers for a second time when West Bromwich Albion stuck by their policy of keeping him until they signed a replacement.
“We will just have to see how that plays out," Coates told The Sentinel, “and we don't know what West Brom's strategy will be on that one either.
“But overall, we are pleased with how things turned out in this window for us.
“Obviously we had the long saga with Berahino, which didn't happen in the end, but we are more than pleased with Bony coming in and we believe he will be a good signing.
“I'm sure Mark will enjoy working with him and we are confident he can replicate his Swansea form with us here at Stoke."
