Captain Garry Monk says Swansea have come "miles and miles" since their 2-0 opening day defeat at Charlton.The two sides meet in the reverse fixture at the Liberty Stadium on Saturday with the Swans in the play-off hunt and Charlton rooted to the bottom."Things haven't gone well for them since then but it's a chance for us to show how far we've come," said Monk."Right now we are close to the play-offs and we've got to really push on now and get amongst it all."Swansea have been the Championship's surprise package this season following their promotion from League One last May.Their flowing, passing football has won them many plaudits in the football world and have beaten the top sides.Those include Reading and Wolves, along with two Premier League scalps in Hull City, in the Carling Cup, and holders Portsmouth in the FA Cup.Now Swansea are just two points off the Championship play-offs and are looking to break into the top six for the first time this season."We've had lessons along the way, but we've learnt all the time from those mistakes and we've progressed as a squad," said Monk, who was sent off in the opening game for picking up two bookings."To perform against Premier League teams the way we have this season with confidence... shows how good this team is and how good the squad is.
