For this achievement you need to win 1 match with your ultimate team club that you created. You can do this either online or offline, which ever suits your needs. The easiest way to do this is play a game on single player, verse an someone you know you can beat and put the difficulty set to amateur which should make it even that more easier (With my starter park I was able to beat Arsenal easily on amateur so it's pretty easy). However if your also doing the "Tournament Victory" achievement it would be easier to just play an offline tournament. That way you'll get this achievement in this first round of the tournament if you win and then you can progress (by winning each match) through the tournament, if you win it the "Tournament Victory" will also pop.
