The Reds beat Southampton 6-1 in the Capital One Cup on Wednesday.
The Reds continued their fine form under the German on Wednesday evening with a highly accomplished 6-1 demolition of Southampton in the Capital One Cup.
It was the latest in a number of big wins for his side, with them having beaten Manchester City 4-1 and Chelsea 3-1 this season.
They also have several players, notably Daniel Sturridge, returning from injury, and Klopp says that strength in depth means they can compete.
“We do not have magic ideas. It's about working hard. You cannot be in Liverpool because of the weather, so it must be because of the football club,” he told Sky Sports.
"We need luck with injuries but the squad is strong enough for us to be challengers.”
"At the moment, we don't have to be any more than that. If you shoot the ball between the posts, it's better than when you don't do it."
Given the way Liverpool are now playing under Klopp, it is hard to write them off in the race for the Premier League title.
They are currently sixth in the table, with 23 points to their name, and have already played most of the big sides this season.
That leaves them just four points behind Arsenal in fourth place, and only six behind Manchester City and Leicester City who are joint top of the table.
That leaves them firmly as contenders, although a place in the Champions League may be a more achievable target come the end of the season.
