Sagbo celebrated his first goal for the Tigers at Everton on Saturday, finishing smartly in the 2-1 loss at Goodison Park.
Tigers captain Davies told the Hull Daily Mail: "Yannick's an ox, I call him 'Le Boeuf'.
"Other than in pre-season, people haven't really seen a lot of him, but we know he's got quality. He's a targetman but he's also got an incredible touch. He can link the play and get in behind.
"He's an exciting prospect and even more so because people don't really know a lot about him. That can be in our favour. It'll take time to adapt fully, mainly because he hasn't played many games, but I believe he's ready.
"He managed to get himself a goal at Everton and played well. The more he plays, the better he'll become. He might get a run of games now and I'm sure he'll want to show what we've been missing."
