And Koumas, who has pulled out of the Wales squad, believes the good start could have been better with a bit of luck; "We've made a good start but it could have been better. If we'd had a bit of luck in the opening game at Everton, we might have had three out of three.
"Some people have got us down as relegation fodder but there's no chance of that. We have a decent team here, some good footballers, and we are not surprised at the start we've made.
"I see us winning a lot of games this season and I just can't see it being a struggle. There are goals in this team, we are confident, and as long as we keep it tight at the back, I'm sure that we will win a lot of games.
"For me, it's great to be back in the Premier League. It's the only place to play, and you look forward to every game."
Premiership action continues on Saturday, as Wigan travel to West Ham which has added meaning after last season and the Tevez fiasco.
