Manchester United boss Jose Mourinho says Premier League experience was one of the reasons why he asked the club to sign Romelu Lukaku.
The Belgium international became one of the most expensive signings of the summer after leaving Everton.
He will take over from Zlatan Ibrahimovic and Wayne Rooney in Mourinho's offensive department.
"He was difficult to get," Mourinho told reporters.
"He is from the Premier League. Obviously there are other good strikers in football, but the Premier League is a very specific habitat. A difficult habitat for strikers and normally they need some time to adapt, but Lukaku has been in the Premier League for five seasons.
"Now he comes to a club with different responsibilities in the right moment of his career.
"He is still a young player but he has years of experience in the Premier League and the Belgian national team. He will go into the Champions League, which was also his main motivation.
"Romelu is not a player that participates a lot in the build-up play. He is a player that normally plays in the last third. We had so many opponents last season that decided clearly to defend, closing spaces, playing with lots of defenders and defensive midfield players.
"We needed a target man, which is not Martial or Rashford. We have good options, good players, but a target man, a clear number nine, one who is comfortable to play in the box, we thought that was Romelu."
