Wales expect England to target their Gloucester wing Louis Rees-Zammit, whose three tries in the opening two Six Nations rounds helped them to victory, when the sides meet in Cardiff on Saturday. The home side expect to have a full squad with the centres George North and Jonathan Davies available again along with the wing Josh Adams and the back-rower Josh Navidi. The full-back Leigh Halfpenny is still following the concussion return-to-play protocols. “Louis has a tag on his head and we expect him to be targeted,” the Wales forwards coach, Jonathan Humphreys, said. “There will be pressure on him but we back him to deal with anything that comes his way. He has just turned 20, is very mature and has grown up since the last Six Nations. “He is well aware of the work-ons he has to do outside scoring tries and he is getting on with them. We have some real selection dilemmas this week and the meeting will take a lot longer than a few months ago. England are a world-class team and we expect the best version of them.” Having overcome Ireland and Scotland, who were both reduced to 14 men when first Peter O’Mahony and then Zander Fagerson were sent off for making contact with an opponent’s head as they attempted a clear-out at a ruck, Wales are seeking the grand slam having beaten only Italy in the 2020 Six Nations. “We know it is on the line, but we are not talking about it,” Humphreys said. “We understand how important the game is having won the first two, but what is essential is that we do not get too emotional. It is important we do not play the game today or tomorrow but on Saturday and we know that we are going to have to be a lot better. It will be a huge task to match England’s physicality. “We keep reminding players about the ramifications of head collisions because of the huge risk of a red card and we work hard on it in training. We were advised on this before the tournament so have been aware of it from the off. We have to make sure we are not on the receiving end.”
