Also, probably a fear of the non stop going on about it if they did win it.
Still though, I'd take an English win if it put Gareth Southgate on top of Manyoo's wishlist if it all goes tits up for Eric Ten Hag early next season!!
Our reaction to winning a few games at rugby world cup, in a sport seriously contested by about 8 nations would suggest we'd match them if we'd won it.
Say what you want about them but their reaction to winning it in 2003 was fairly muted. They made more of a fuss about winning the Ashes for the first time in ages, a couple of years later!
