Gibson crossed twice for England Under-20s in their high-scoring defeat of France
London Irish No.8 Jamie Gibson notched two tries in 12 first-half minutes as England ended their RBS Under-20 6 Nations Championship on a high with a 47-33 win over France.
Gibson crossed the whitewash twice in the opening 12 minutes to set England on their way with Tom Casson, Marcus Watson and Sam Smith adding scores after the break.
Tom Homer converted all five tries and was equally as impressive as Gibson also slotting four penalties as he ended with a personal tally of 22 points.
France also touched down five tries thanks to a double from scrum-half Alexis Bales and singles from Lucas Dupont, Xavier Chiocci and Arthur Roulin.
However their kicking wasn't as good as London Irish full-back Homer's with Jean-Marc Doussain and Gilles Bosch recording just two conversions each at Saint Nazaire.
England needed to win by nearly 50 points to overthrow leaders Ireland and did their best to make the seemingly impossible possible in France.
Gibson got England off to a flying start charging down Doussain's attempted clearance and racing away to open the scoring after just 60 seconds.
The London Irish No.8 was at it eight after 12 minutes finishing off Casson's 40-metre break before France hit back with a scores through Dupont and Bales.
England responded with two Homer penalties but allowed France to score a third try after loose-head Chiocci barged his way over.
Homer sunk a third penalty with French hooker Mickael Ivaldi in the sin bin for killing to ball in his own 22 to move the scores to 23-19.
England flew out of the blocks after the restart and three tries in 12 minutes settled the tie.
Watson and Casson finished off sweeping multi-phase attacks from England's own 22 while Rory Clegg made the most of a turnover finding Smith in space with a cross-field kick.
Tanguy Molcard and Joe Marler exchanged yellow cards late on with France taking full advantage with Bales chipping and chasing for his second before Homer slotted a fourth penalty.
