Not really the best game to judge Mahrez's abilities, but thought he looked pretty assured, and looked the most potent attacking threat of an Algeria side that didn't offer that much.
Will be interesting to see them go up against Russia and Korea because neither of those were convincing.
They need to win now so we should get to see more of his natural attacking flair .... they were desperate not to get beat yesterday but came up short as Belgium's quality eventually came through ...
