The 25-year-old, who joined the Magpies last season from Chelsea after arriving in England in 2013, scored his debut league goal against Stoke City in a 2-1 victory on Saturday. The result made it three wins in a row for his side.
“I think in the Premier League there is more quality. If you make one mistake you get punished so you have to concentrate," Atsu was quoted as saying by Chronicle Live.
“I’m very happy to be playing now and helping the team. For me, the longer you play the more you learn in the Premier League.
“I’m trying to improve myself and also the team now. I was looking for my first Premier League goal and got it against Stoke so I was really glad,” he added.
Atsu also revealed that his teammates are prepared to fight for each other to maintain their recent fine form.
“We’re very happy with three wins in a row. We lost the first two games so this shows that we have a very strong mentality in the dressing room. We all want to improve every day, so we just need to keep working hard and improve the team.
“We are ambitious and have a strong mentality where we fight for each other. We support each other. That’s what we did in the Championship and what we will now do in the Premier League.”
Atsu is expected to make his fifth start of the season on Sunday when they travel to the American Express Community Stadium to face Brighton and Hove Albion.
