Something of a surprise inclusion in the squad after edging out Six Nations winner Mefin Davies, Titterrell may well be on the small side but that has hardly harmed Neil Back.

Indeed Kingsley Jones, the former Wales captain who is Titterrell's forwards coach at Sale, is convinced the 23-year-old could well be the long-term successor to Back despite having spent the vast majority of his career to date at hooker.

So confident is Jones that he has not been shy in throwing the Kent-born forward into Zurich Premiership action on the open side this season and while some do not share his belief, it is easy to see how he has formed his opinion.

One of the fastest forwards in the world game today with impressively quick feet, Titterrell would solve England's line-out wobbles in a flash with his almost faultless throwing in stark contrast to Steve Thompson's often slapdash efforts.

He may not have Thompson's brute strength - no surprise given the near four-stone weight difference between the duo - but he has plenty of power in his frame and gives Sir Clive Woodward options, particularly against tiring defences.

That is how Woodward used him last summer when he made his Test debut against New Zealand and he immediately adapted to life at the highest level, rattling the All Blacks with his trademark darts from mauls and rucks.

Likely to start behind at least Thompson in the pecking order, but his new-found versatility could earn him a place on the bench for Tests in what will surely be the most memorable summer of his life, with his wedding to fiancée Del to follow this tour.
