The 20-year-old Nigeria international was thrown into the heat of Sky Bet Championship battle for the first time in Saturday's 0-0 draw at the Keepmoat Stadium having watched patiently from the stands since his arrival on loan from Chelsea on January 7.
Omeruo told the Evening Gazette "I have watched a lot of Boro games over the past few weeks and I know that this is a very, very tough division.
"Every team fights from the start to the finish and there is no let-up in any game. It is a real physical battle for 90 minutes and more and you can't switch off for a second.
"When I was picked for the team, I knew that I had to switch to that same mentality straight away, and I think I did that.
"It was a tough game, but I think I played well. I love to play. I was just disappointed that my first game was not a win."
