The OP is complaining that he only won 3-0 buddy, he had 78% possession.
I don't know what he is complaining about, unless he expected to win 9-0.
Barcelona regularly win 3-0 or 4-0 vs. bottom table La Liga opposition, and you could say Barca are a 7* team, whilst Celta Vigo for example are a 3* team.
I don't see the problem?
