The 28-year old Sierra Leone forward has impressed during his loan spell with Norwich City and could either remain at Carrow Road or move elsewhere depending on whether or not the Canaries want to retain his services.
"If he's going to come back obviously we'll welcome him with open arms, he's part of our club, but let's be honest, ever since he's gotten fit (at Norwich City) he's started every game and they've had some success with them on the field," Sporting KC head coach Peter Vermes told Soccer By Ives.
"What has really come of it, and they don't have to make a decision until May, but what's really come of it is we have two other teams in the EPL have reached out to us and the league, and we have a few other teams from France.
"He's now in an envious position because I think he's going to have a lot of suitors come here in a short period of time come the summer window."
Vermes added: "(Norwich City) have an option, but if they slow up the process it's a simple one. We have other suitors so we can go that way pretty quickly. They're going to have to make some decisions, and we're evaluating the other interest that has come in.
"We signed Kei to an extension so it's not like we're trying to hurry it up because we can still have him for the rest of the year, Vermes said. "It's not the summer window," Vermes said. "We did that on purpose because we wanted to make sure that they weren't trying to stretch us out while we're trying to do other deals."
