Icardi's three goals led French champion PSG past 10-man Saint-Etienne 6-1 and into the semi-finals.

The Argentina international forward has flourished since arriving on an initial loan deal from Serie A club Inter at the start of the season, scoring 17 goals across all competitions.

PSG midfielder Verratti hailed Icardi – who was linked to Juventus, Napoli and Real Madrid prior to joining Thomas Tuchel's side – after his latest exploits in Paris midweek.

"Mauro? He may not touch the ball, he knows the ball will reach him and he will score, he is always ready," Verratti said. "This is his main characteristic of Mauro. We didn't think it was going to be as good, the first six months are always difficult, but it is incredible and we hope it will continue like this."

Icardi has hit the ground running in the French capital, with nine of his goals coming in Ligue 1 as defending champion PSG tops the standings by seven points.

"Starting the year well is important for everyone and for the team," Icardi said. "We already did it with the last match in the Coupe de France, we demonstrated the team we have. And today, at home, we once again demonstrated the team we had, facing another opponent, by making a great match.

"The fantastic four [Icardi, Kylian Mbappe, Neymar and Angel Di Maria] ? We are working to improve, to have an oiled collective game, to attack together, to defend together, to do it in the best way. We know what we have to do. That's why we will have good results.

"We know that if we want to play with four forwards we must all make the sacrifices together. And that's what we've been doing since the coach changed systems. And we're doing it very well. "
