England host Wales at Twickenham on Sunday in a Six Nations game that's crucial to both sides' title hopes.
Wales coach Warren Gatland has made two changes to the side that beat France last time out with two of their most influential players back in the mix.
Alun-Wyn Jones missed the France game because of a toe injury but Scott Quinnell says it is centre Jonathan Davies' return that will lift the whole team.
"This is an incredibly strong Wales side, who have an incredible amount of game time and caps," said Quinnell on Sky Sports News.
"Jake Ball did particularly well against France but it is great to have Alun-Wyn Jones back - he is a world-class player.
"Then there is the feel-good factor of Jonathan Davies coming back as well. He has not played a lot of rugby, and he probably won't go the full 80 minutes. He brings that cultured left foot of his into play and he will make everyone else around him feel good.
"Against France the pack went very well which allowed Rhys Webb to play his particular game. He has a quick pass and he got the back line going. It is very exciting.
"That loss against Ireland may just be what they needed. Perhaps it was the game to get Wales back on track. The one thing Wales can and do is turn up for the big games.
"England have the players upfront to cause Wales a huge amount of problems. After everything that happened to Dylan Hartley over the summer I think he has come back a better player - he has been playing some wonderful rugby.
"For me Sunday's game is all about the front five - whoever wins that battle will go a long way winning this game."
Will Greenwood agrees that Wales are an exceptional side but questions how long they can keep on putting in world-class performances.
"Jonathan Davies is world class, absolutely world class and that mid-field combination of him and Jamie Roberts, when fully fit, will take on anyone in the world," he said.
"Alun-Wyn Jones is a warrior and the Wales side is full of confidence and is mentally tough. But I think they can be exposed by a bit of pace by England on Sunday in terms of the momentum, the tempo and the intensity. I just don't see how Wales can keep on going to the well.
"These players have been so good for so long - the Lions is such a big emotional roller-coaster, a real physical and mental roller-coaster.
"I think that with Danny Care in at No.9 lifting the tempo and the defensive pressure that Owen Farrell will lead - he will be comfortable trying to shut down Jamie Roberts when they send him down that No.10 channel - that it will be too much for Wales.
"No matter what the track records are, I think England must start this game as favourites."
