Marler started his career at Haywards Heath RFC in Sussex where he played in the same side as fellow England international Billy Twelvetrees.

After joining the Quins academy in 2008, the prop spent some time on loan to Esher and Worthing

Despite failing to cross the whitewash in his 66 caps since making his England debut in 2012, he did score in one of his two appearances for the British & Irish Lions during the 2017 tour to New Zealand.

He's been nicknamed Croissant. In his own words, it's because: “The boys think I have a nose that looks like a French pastry.”

Marler was captain for England at U18s level and represented the U20 squad throughout the Junior World Championship in summer 2009.

He is obviously a fan of Friends, except he added his own twist to it by choosing two ducks instead of having a chicken. 

Marler is happily married to long-term partner Daisy, with whom he has three children. Jasper, 5, and Maggie, 3, were joined by another new born just before the World Cup commenced.
