While Philogene had to drop down a division, he has shown his quality and contributed to 14 of Hull's league goals this season.
Villa do have a buyback clause, with the Tigers' vice-chairman Tan Kesler explained to Hull Live: "It's pretty simple. The buy-back clause can be interpreted negatively or very positively.
If the player is yours and you feel you don't have the right to control it all the way along (through the contract) but you can also look at being able to get that kind of talented player you create a win-win situation, and share certain rights so that you can get it done and beat the competition.
"What we did in my opinion and for our fans to (understand) our decisions for the future, we're not just buying players and then their previous clubs can buy them back from us, it's a mechanism where we create a win-win situation.
"There is a value that has been put on an identified performance, which is good. Maybe he can never reach there or he can bypass there, but at least for the market, for the industry, we know what he can be worth to leave our club. If someone comes in and offers less than his buy-back value, do we consider it? Should we consider it? Probably not. It's a good thing. And having another big club on your side and being able to have some part in Jaden's development plan is good.
"If we promote, Villa have the right to buy him back for 15m. Having said that, if we have another offer that's worth more than 15m then we would have the right to discuss it, it's not like we're forced to sell to Villa but they would have the first choice and that's part of our agreement.
"That's how Keinan Davis was going to come, and in the future, you might see more players coming in - from Roma, more from Villa, we're in the process of establishing more relationships - like this to help us get to promotion level. From there on, it's about the club, it's about the process. It's not about individuals, but it's about individuals participating in the club's success.
"We want to have the culture for our fans, for everybody else. The club is the main focus. We said from the beginning that we wanted to be the most communicative club with its fans, and in this case, the fans and the club are most important. If Jaden comes in and helps us - I know we're talking about Jaden, but we'll talk about many other players who are also very important - to our success, he's a key part of that, not the main part."
