"We know not to take anything for granted against Wigan because two points slipped away against them last season of course," he told the club's official website.
"It was a bad game. I think we deserved to win but anyway, you have to score a second goal and finish the game if you want to avoid these situations.
"We know the Premier League is very difficult and all the teams have something and can be strong in the air and play with determination. When they come to Anfield you know it will be really difficult so we have to be alert and be careful next time.
"But the team has more confidence now and I think we can approach the games thinking about just to finish it as soon as possible."
