Classy Mbappe secures league for Monaco
Monaco 2 St Etienne 0
Kylian Mbappe set Monaco on their way to wrapping up the Ligue 1 title as they secured a 2-0 win over St Etienne.
Europe's most exciting teenager grabbed his 15th league goal of a sensational season to help the principality club clinch the championship with a game to spare.
Valere Germain put the seal on the win with the last kick of the game to really get the party started.
The hosts kicked off knowing a point would be enough to win a first crown since 2000 and end Paris St Germain's four-year domination, and Mbappe was a fitting hero as PSG were condemned to finish in second spot.
St Etienne started brightly, but Monaco's nerves were settled after 19 minutes when the visitors lost the ball in midfield, and in a flash found themselves behind.
There was no catching France's young player of the year Mbappe as he raced onto Radamel Falcao's through-ball. The 18-year-old put goalkeeper Stephane Ruffier on his backside with a drop of the shoulder before rolling the ball into an empty net from an acute angle.
Falcao saw a goalbound volley blocked after being teed up by another breakneck run from Mbappe.
St Etienne did threaten through Florentin Pogba, who had a free header but planted it straight at Danijel Subasic.
Monaco had more scares before Germain rounded off a swift counter attack to start of the celebrations.
