Arthur Rowe
I think Pepe is another one similar to Vardy, and like you point out Mahrez. Pepe started 6 games and was a very important part of the Portugal team that won the European Championship. Just months after he started the CL final they won and he's been an important part of that Real Madrid team too.
It doesn't make him one of the best 30 footballers in the world, but it does make him one of the 30 footballers in the world with the best 2016.
he gets plenty of attention for his antics but he's a great defender too
