Liverpool is reaping the benefits of its decision to play hardball with its best player.
Suarez missed the first five rounds of the Premier League while he served the remainder of the second ban of his career for biting, but he is still the division's top scorer with 13 goals in nine games.
"When I am happy off the pitch you can see it (on the pitch)," Suarez is quoted as saying on the website of Spanish sports daily Marca on Thursday. "I am happy in the Premier League, it's the best league there is.
"Luckily, I am scoring goals now to make up for the games I missed. I am getting back my confidence and helping the team. The important thing is that Liverpool finishes in the top four after a long time not doing so. I am going to help the team do so."
And Liverpool manager Brendan Rodgers also thinks the difficulties of the summer have been overcome.
"I think he is the happiest he has been here," Rodgers said. "He flies all around the world but I think this club suits him perfectly and I still think his best years are going to be here.
"The profile of the club, the connection with the supporters, you can see it is a hand-in-glove fit for him."
Not everyone will want him to stay in the Premier League, though. Norwich's players, for example, can't wait to see the back of Suarez, who has scored 11 goals and three hat tricks in four games against them.
"I wish Suarez would just leave us alone," Norwich midfielder Anthony Pilkington said. "Big bully."
