There's a video on this webpage that will teach you how to make the L-sound:

"Valmy" is two syllables: val MEE (stress on the second syllable)

The second sentence is incorrect. You can choose either of the following, but you can't mix the two!

England is playing France in football ...
or
England's players are playing France's playersin football ...
