Swansea goalkeeper Michel Vorm has revealed his satisfaction at his side's progress this season following their defeat of Manchester City on Sunday.
Luke Moore's header in the 83rd minute saw Roberto Mancini's City knocked from the top of the Premier League by local rivals Manchester United, a result which is arguably Swansea's most impressive since their elevation to the Premier League.
The Holland international must have feared the worst when his side were beaten 4-0 by Manchester City earlier this season, but he believes their ability to hit back and beat the very best shows how far Brendan Rodgers' men have come.
"You can see the progression we have made since the first game against them. We don't panic if we don't score in the first half. We just continue to play our own game," he said.
"At the beginning of the season we drew a few games 0-0, but now we win those types of matches. If you want to beat the big teams you have to be patient and we showed that."
Swansea, who were promoted last season as Championship play-off winners, have made the Liberty Stadium a fortress this campaign, taking eight points from 12 in games against Manchester United, Manchester City, Tottenham and Arsenal.
The former Utrecht shot-stopper said: "When I came in everything was new, but I knew from the first match we had so much quality and belief in this team. The supporters are really into Swansea. The whole city is proud."
Vorm went on to admit Swansea are even being mentioned around Europe following their debut season in the top-flight.
"After the Arsenal game we really got the respect we deserved," he added. "Now everyone is talking about Swansea - even in Holland. Brendan has made us believe and with the quality we have and we know we can beat anybody.
"Proud is a good word to describe how everyone is feeling here."
