Crystal Palace boss Ian Holloway has lavished praise upon Swansea City by revealing that they changed his entire perspective about the way to play football.
The Swans, fresh from their 3-0 victory over Valencia, make the trip to Selhurst Park on Sunday.
After being sacked by Leicester City in 2008, Holloway watched the Welsh side on a number of occasions and was impressed by their attractive passing style.
"Swansea have changed how I see the whole of football," he told reporters.
"When I was sacked by Leicester I went to watch four or five of their games and what they made me realise was how beautiful the game is and how passing and moving can make you a better defensive unit.
"Swansea will be heavy in possession and will move us around and try and play and that is a challenge."
In 2011, the 50-year-old got Blackpool promoted to the Premier League and won many admirers for their attacking football.
