You're not going to see a better assist than this all year. Dimitri Payet might have been the best creator in the Premier League last season, and he's picking up where he left off by supplying incredible crosses like this one. Look at this perfect, pinpoint rabona.
West Ham fell apart and got wrecked by Watford after that, but it's not Payet's fault. This is a rare case where the result of a game shouldn't overshadow an individual play, because this assist is that special.
