Champion Francesco Molinari: "I've been so close many times and to finally get over the line is amazing. As you can see on 18 it wasn't easy. I can't wait to come back and defend the title. It's such a great event.
"The Ryder Cup is very special. It hurts to watch it on TV. You really want to be there. I've been lucky to be on two winning teams and I hope to be able to win a third time."

Jeff Murray: Rory hasn't had the mental strength and consistency to win big tournaments for a number of years. He could end up being one of golfs greatest underachievers, with his ability he should have won more tournaments/majors by now. So frustrating to witness.

Francesco Molinari
hasn't claimed a title since he won on home soil, the Italian Open, back in late 2016.
But
this will be his fifth European Tour title, drawing him level with Constantino
Rocca for the most wins by Italians on the European Tour.
A £1m too
for his troubles. But more importantly, he's thrust himself into Thomas
Bjorn's thoughts for the Ryder Cup in September.
