However, the Nigeria international insists dropping into the Championship isn't on the agenda.
On Slutsky, who he worked with at CSKA Moscow, he told TASS: "He is like a father to me. He believed in me and made me who I am now. Yes, I spoke to him about a possible switch to Hull and I could not refuse him. So maybe I'll work with him again in the future, but Hull plays a division lower and that's the problem, I think.
"I have also read that I can go to Spartak, but that's impossible, because I'm a big CSKA fan and do not see myself playing Spartak. I hope I get the chance to return to CSKA, I would love to do that.
"CSKA will always stay in my heart, I will always love that club. I'm proud to have played at such a club and it was a difficult decision to leave. But I am also lucky to be at Leicester now. Yes, I play little, but this is sometimes the case in football. Sometimes you just have to find your place if you're new to something.
"I'm working very hard to get back to my top level."
