The Croatia striker, signed from HNK Rijeka for an initial ??7.5m, came on as a substitute in City???s1-0 home defeat to Stoke in the Premier League last week but hardly touched the ball.
Despite that inauspicious start to his career at the King Power Stadium, Pearson is convinced the 23-year-old has what it takes to be a success in English football as they prepare to face Tottenham in the fourth round of the FA Cup on Saturday.
“I’m very satisfied with Andrej. We are delighted to have signed him, a player we had an interest in over a long period of time,” said Pearson.
“It’s been very impressive how he’s dealt with his situation because it’s never easy for a young man to be patient waiting for the political side of getting a deal done, with work permits etcetera.
“But he is settling very well, his English is excellent, so that’s a great benefit for him in terms of being able to understand what’s expected.
“The most important thing for him is that he’s been able to settle in with his team-mates, and I’m sure he’s enjoyed his experience so far.
“Clearly we would have liked his debut to have been a more positive experience, but I’m very confident he will have a real effect on the team’s fortunes here on in, and that’s the most important thing.
“He’s an intelligent player, and I’m confident he can have a positive effect on us pretty quickly, but I’m also aware players need a bit of time.
“We’ll try and make the transition for him as easy as possible, but ultimately we think he’s good enough to do that as quickly as he can.”
As for the trip to White Hart Lane in the cup, Pearson is convinced success there could help boost confidence in the camp and with it their chances of retaining their Premier League status.
“I’m the first to admit we didn’t play as well as we could do last weekend, we didn’t hit the levels we had been doing,” added Pearson.
“Clearly it would be nice to progress in the cup because winning games for us, in whatever competition, is going to be beneficial.
“But it’s not going to be an easy tie for us as Spurs have an awful lot of options, particularly in attack.”
