London - Swansea City are becoming a force in the Premier League after maintaining their unbeaten start with an impressive come-from-behind 2-1 victory over Manchester United, manager Garry Monk said.
Sunday's win was Swansea's third in a row against United and extended an excellent start to the season which began with an opening-day draw at champions Chelsea.
"We're a good team," Monk told Sky Sports.
"We're a force in this league and when we're on it and playing our best football we can be unbelievable.
"When we weren't playing our best we can do the other side and that's the key to being a good team."
The Welsh club were promoted to the Premier League in 2011 and consolidated their top-flight status under first Brendan Rodgers then Michael Laudrup.
They won the 2013 League Cup, their first major silverware, but Laudrup was dismissed and replaced by inexperienced Monk in 2014 - his first managerial role.
Monk, however, defied the odds by finishing eighth last season with a club record 56 points and Swansea have started this campaign in eye-catching form.
"It's just the way that we work and the stuff I try put in place with he players on the field and off the field we work a lot on our mentality and the way we approach games," said Monk, who has continued the club's recent tradition of possession-based, neat-passing football.
"Today you saw character and the technical side of it. You've seen in the games already this season we've performed unbelievably well and in different ways and shown every side of us. That's what a good club should be doing."
