At the beginning of the 2013–14 season Davis went to San Francisco to train at the Massialas Foundation with USA national coach Greg Massialas. He achieved two quarter-finals in World Cup events. At the European Championships in Strasbourg he had a close win against young Alexander Choupenitch of the Czech Republic, then overpowered 15–8 Peter Joppich and met Aleksey Cheremisinov in the final. Davis was led 10–6 when the referee interrupted the bout: with temperatures above , his sweat-drenched jacket was registering false positives. Davis was able to refocus after changing his kit and won Britain's first European foil gold. Cheremisinov took his revenge in the team event, where Russia disposed of Britain in the quarter-finals. At the World Championships in Kazan reached the quarter-finals, where he was defeated 15–6 by France's Enzo Lefort. In the team event, Britain were largely overpowered by Italy in the quarter-finals and finished 8th. Davis ended up world No.6, his best ranking so far.
