Swansea City have completed the signing of Argentine defender Federico Fernandez from Napoli.
The centre-back has penned a four-year deal with the Welsh club.
Swansea skipper Ashley Williams admits he is not fussed by the Louis van Gaal factor at Old Trafford on Saturday.
– Swansea captain Ashley Williams
We couldn't really have got a bigger game, but the spotlight is obviously with them as they've got a new manager and it's on their ground.
We won't worry about them. We've been working on a system, how we want to play.
We need to concentrate on that really and go into the game positive.
For us, we're just concentrating on ourselves, whoever the opponent is.
Swansea have confirmed the departures of Spanish pair Chico Flores and Pablo Hernandez for undisclosed fees.
Both players will play in the Qatari Stars League with centre-back Flores linking up with former Swansea manager Michael Laudrup at champions Lekhwiya and midfielder Hernandez joining Al-Arabi.
Both transfers are subject to international clearance but the moves will end two-year spells for the Spaniards at the Liberty Stadium.
Lukasz Fabianski says that fear will not be on Swansea's agenda when they open their Barclays Premier League campaign against Manchester United at Old Trafford on Saturday.
– Lukasz Fabianski speaking to the official Swansea website
It's not going to be an easy game for them. We are going to give our best and try to win it.
We are going to be well-prepared for the game and it's going to be very interesting.
There is no point to fear the opposition, especially as Swansea beat them away in the FA Cup (last season) so we should not be fearing anything.
They are a big club, but we are going to go there and try to get some points. That's our aim.
