The pair are yet to taste defeat at Ibrox and Gerrard believes there could be even more to come.
“When I brought those two players in, knowing their characters, I didn't really expect them to settle so quickly," he told the Daily Record. “I thought it might take them two or three months for them to settle into the city.
“They are both young lads coming away from their families to live alone and have joined a huge club with big expectations and big pressures.
“But they've settled a lot quicker than I thought. I'm absolutely delighted with both of them.
“I thought Thursday night [Rangers defeated FC Ufa 1-0 in the Europa League qualifier] was Ovie's strongest performance yet. Over 90 minutes I thought he controlled the game. He ran it, he looked great on the eye and did a lot of nice stuff that people would have liked.
“But he also did the stuff I like from a midfielder. He competed well, he regained the ball, he pressed hard and that's been coming from his previous two performances.
“So Ovie's in a fantastic place. I think he and the fans can grow together and have a relationship there. He'll entertain them but he's also an honest kid, so I'm really pleased for him.
“Kenty has also settled really quick. He's doing both sides of the game. He's defending well, tactically he's really clever - which people might not realise - and he also gives us an unbelievable threat with his pace and skill.
“When things start dropping for him a bit more he'll continue to grow. A little bit of luck hasn't gone his way in terms of getting a goal or pulling off a little bit of magic but I think it's really close."
