England vs Wales. Friday, 11 March 2016, kick-off 19.45
Go down the M4, across the Severn and turn right down to Bristol. By car from Cardiff it takes just over an hour. That is the small journey that Wales Under-20 will do to play England in this vital match. The 16 000-seater stadium is the home of Bristol City and Bristol RFC.
England made five changes. Loosehead Lewis Boyce returns to the side from a knee injury but Joe Marchant is wanted by Harlequins who play Bath at The Stoop. Charlie Thacker moves to outside centre with George Worth coming into the centre inside of him. George Nott moves from lock to flank and Andrew Kitchen comes into lock.
Wales have made three changes from the team which beat France in France and they are changes calculated to strengthen the team. Owen Watkin is back from Ospreys duty to play outside centre and Daniel Jones is back from Scarlets duty to play at flyhalf. In the third change Harri Millard moves from inside to outside centre.

England: 15 Max Malins, 14 George Perkins, 13 Charlie Thacker, 12 George Worth, 11 Ollie Thorley, 10 Mathew Protheroe, 9 Max Green, 8 Callum Chick (captain), 7 Sam Smith, 6 George Nott, 5 Andrew Kitchen, 4 Huw Taylor, 3 Will Stuart, 2 Jack Singleton, 1 Lewis Boyce

Scotland vs France. Friday, 11 March 2016, kick-off 20.00
This is a big match for two strong sides. Earlier this year Scotland had their first win over England, beat Italy and just lost to Wales by a last-minute penalty.
Scotland have made six changes, two positional. The most noteworthy change is the return of powerful tighthead Zander Fagerson who won a senior Scottish cap against England in this year's Six nations. Flyhalf Adam Hastings has been released by Bath and is back in the side. To accommodate him Rory Hutchinson moved to outside centre. Hooker Jake Kerr is back from injury and hooks while Andrew Davidson moves from lock to flank and Callum Hunter-Hill takes his place at lock.
It looks a stronger Scottish side for the changes.
France looked weakened with Gabriel N'Gandebe suspended and wing Alex Arrate and inside centre Elliot Roudil injured. This has meant three changes to the back. Two of the three loose forwards are changed as Alexandre Roumat and Matthieu Voisin come in to improve the pack's mobility. Thomas Lièvremont has made two changes to the front row with a new hooker and a new tighthead.

Scotland: 15 Ruairi Howarth, 14 Ben Robbins, 13 Rory Hutchinson, 12 Tom Galbraith, 11 Darcy Graham, 10 Adam Hastings, 9 Hugh Fraser, 8 Ally Miller, 7 Matt Smith, 6 Andrew Davidson, 5 Scott Cummings (captain), 4 Callum Hunter-Hill, 3 Zander Fagerson, 2 Jake Kerr, 1 Murray McCallum
