Dai Young was pleased to see his Wasps side maintain their unbeaten record in the Premiership at the Ricoh Arena on Sunday.
Wasps outscored Gloucester by five tries to two in their 32-21 victory in Coventry.
The club have now won four straight league games at their new ground since the move from High Wycombe, even if Sunday's performance wasn't a vintage one.
"Something we have talked about is to keep our home record in the Premiership intact, which is hugely important for us," said Young.
"But I have to be honest, it was a pretty scrappy performance from us. We were very ordinary in parts but to come away with a win, let alone a bonus-point win, I am really pleased.
"Yet we have to be honest with ourselves and, while we showed glimpses of some good stuff, we were sloppy and put a lot of pressure on ourselves as well. We know we have to be better than that."
Thanks to their try bonus point Wasps also move back into the playoff positions, but Young said that even making the top six in the league this year was difficult enough.
"People keep talking to me about being in the top four. Forget about that. It is so tight that top six is a mountain to climb.
"Last week, we had a draw in Newcastle and went from fourth to seventh. My concern is to do everything to get into that top six and that is still not a gimmie."
Gloucester director of rugby David Humphreys felt his side lacked the required execution to put Wasps away.
"We lacked composure and when opportunities come, Wasps are probably one of the best in the league at finishing off small chances.
"We just have not got that killer edge yet and that is something we want to work on.
Humphreys also gave credit to axed England winger Jonny May for his attitude after being understandably disappointed earlier this week.
"It has been a difficult week for Jonny but credit to him, he has come into our group and brought huge enthusiasm to the training group. He was looking forward to playing today and he nearly set us up for a typical Gloucester try from nothing."
