Anthony Martial's superb start to life in the Premier League is no surprise, according to Monaco captain Jeremy Toulalan and manager Leonardo Jardim.
Manchester United boss Louis van Gaal spent big money on bringing the striker to Old Trafford - Monaco say they could end up receiving almost £58m for the teenager.
But he has scored four goals in six matches for United, including a superb solo effort on his debut against Liverpool.
Martial's immediate success came as a surprise to many in England, but not his former captain at Monaco.
"No, it is not a surprise for me," Toulalan said. "Anthony has got a lot of qualities.
"He is a good man and he will have a lot of success in Manchester.
"For Anthony, to be honest, it was difficult to refuse an offer like this. I am happy for him, he plays well at Manchester United."
Martial moved to the principality from Lyon in 2013, making 70 appearances and scoring 15 goals for Monaco before heading to Old Trafford.
Jardim, like Toulalan, completely understood the striker's desire to move on and has not been surprised by the way he has begun life at United.
"Anthony is a very good young player," the Monaco boss.
"Last year he played badly in the beginning of the season and after worked a lot physically and mentally.
"When you work in a club like Monaco with good methods and a good team, it is easy to improve - and then go to a big European club."
