At the grand old age of 18, Kylian Mbappe has the footballing world at his feet.

The mother of all breakthroughs with AS Monaco last season saw Mbappe procure the Ligue 1 title and grace the Champions League semi-finals. Accumulating 44 appearances and 26 goals, the Frenchman is already a Ballon d'Or nominee.

That one world-class campaign was all the 18-year-old needed to attract the attention of his home club - Paris Saint-Germain - who captured him on loan for the season, with an obligation to pay €180 million next summer.

You can't exactly say Mbappe has experienced a bad start to life at the Parc des Prince, either.

As part of a formidable attacking triumvirate with Edinson Cavani and Neymar, the Frenchman has settled in soundly and has already provided four assists.

On the goal scoring front, you can't exactly have many complaints with Mbappe finding the net three times in six appearances for PSG.

Consequently, it seemed an understandable tactical decision for Unai Emery to deputise Mbappe as a central striker against Dijon on Saturday after Cavani was given extra rest for his international duties.

For a man so revered for his offensive contributions, it was a pretty nondescript performance only saved by a few moments of skill and sullied by bizarrely poor finishing.

After the game, Mbappe lamented: "It was not easy because I have not played in this position for a long time.”

That's putting it mildly. PSG required two goals from the unlikely source of Thomas Meunier to bail themselves out against a team stewing in the relegation zone.

Mbappe managed to miss an open goal on two occasions, first blazing over on the volley and then by flattering the Dijon goalkeeper with a scuffed finish in front of a gaping net.

Check out his highlights below and the poor misses at 3:05 and 3:57, below:

Edinson Cavani would tuck those away with his eyes closed.

Of course, this is an 18-year-old starlet we're discussing here and Mbappe has given fans more than enough evidence of his class, but even he will admit that his performance as a striker was poor.

The Frenchman will need to polish his finishing in Paris to compete with the likes of Neymar and Cavani or - at the very least - find the net when there's no goalkeeper to beat.
