Guehi moved to City from Crystal Palace last week and made a winning debut against Wolves on Saturday.
However, he could so easiily have been playing for Liverpool this season before Palace pulled out of the deal hours before the summer deadline.
Speaking for the first time about what happened, Guehi said: "The medical was pretty much done, and then it got pulled at the last minute.
"So, yeah, I was quite close (to joining Liverpool). I was OK. Yeah I was OK. My mindset is always move on to the next one. God's got a plan for me. Just focus on what I could do for Palace.
"I can't speak on anyone's behalf or about anyone else's decision. That's their life. But getting bought by Palace was such an honour, a blessing, so it would be doing Palace a disservice if I was acting a certain way.
"The least I could do was show up to work every single day, shut my mouth and keep my head down. I think that's most important. I'm just glad that I got to move over the line. I'm really confident that this is the place for me to improve, to grow as a player. So I'm glad I could get over the line."
