I think you're all missing someone here fellas. Messi is nothing when compared to Brighton's very own Paul Molden: Born in Farnworth, near Bolton, Lancashire, as a youth Moulden entered the Guinness Book of Records by scoring 340 goals in a single season for Bolton Lads Club under-15s...
Out of interest how did you come to this idea? I must admit I'm not an expert on Muller but he was a very different type of player. I do not think you can compare them; all you can do is compare stats and medals and accept and enjoy both of their outragous talent.
