Crystal Palace boss Sam Allardyce says he has known his West Brom counterpart Tony Pulis for a long time, and he believes his 'tactical genius' is underrated.

"Tony and I are good acquaintances," said Big Sam. "I've never been mate mates, but we've known each other a long time & always have a chat when we see each other.

"Outside of the top boys Tony probably gets more clean sheets than anybody else and now the goal tally has gone up.

"Instead of getting praise for being a tactical genius, he gets criticised for the way he plays when beating the big ones."
