AS Monaco boss Leonardo Jardim has paid tribute to Kylian Mbappe after watching the forward score twice in Wednesday's 3-2 win over Borussia Dortmund in the Champions League.
Mbappe's brace in Germany has placed the Ligue 1 side in a strong position to make the semi-finals of the European Cup ahead of next week's quarter-final second leg.
The 18-year-old has now scored 21 times for Monaco in all competitions this season, with his form believed to have attracted interest from the likes of Manchester United and Real Madrid.
Jardim has backed Mbappe to reach "a very high level", but has called on the France international to continue working hard as he develops in the European game.
"Mbappe is progressing a lot. He has been with us for over a year, almost two years. He works well, he progresses and understands his role during matches," Jardim told reporters.
"We are happy with his performance. We had prepared for this match: maybe he didn't play against Angers for that, too. I think he's going to get to a very high level. But, as always – I speak to you like I do to him – it is always the work, the progression that will help you to reach a great level."
The second leg of the European quarter-final will take place in Monaco next week.
