Giggs has temporarily taken over first-team duties at Old Trafford following the departure of David Moyes and made a perfect start by masterminding last weekend’s morale-boosting 4-0 victory over Norwich City in the Barclays Premier League.
Brown, an ex-Red who played with Giggs between 1997 and 2011, has been impressed by the 40-year-old’s performance so far and is braced for a difficult match in front of a partisan crowd at the Theatre of Dreams.
“I watched his first game and United played really well. Everyone was up for it and, in that context, he has done fantastically,” Wes told SAFC.com. “Against us, we will obviously go there and try to get three points but we know it is going to be very difficult.
“I have always thought that Ryan would eventually manage a team and, although it is under bad circumstances in the way that he has gone in, I am sure he is thriving on it and looking forward to the next few games ahead.
"Everything at the moment is going to be in their favour. They have got a new lease of life, they will definitely be up for the game and the crowd will as well.
