London - Icelandic midfielder Gylfi Sigurdsson believes Louis van Gaal's Manchester United team are a different proposition to the one that the Swans faced on the opening day of the English Premiership.
"While it was a fantastic result at Old Trafford for us, United are different now," Sigurdsson said.
"They are more settled and are winning games and grinding out results - like we saw at Preston in the FA Cup on Monday.
