The 2-1 defeat to Garry Monk's side at Old Trafford was a stark reminder than the former Netherlands boss still needs to strengthen his squad before the end of the transfer window.
One area where Van Gaal looks to have top class options though is up front, where Robin van Persie and Wayne Rooney should provide the United line up with plenty of firepower.
New Paddy Power customers can back the England international at 9/2 (5.50) to score anytime, a massive enhancement from the online bookmaker that is open to any customer opening a new account.
Last season Sunderland dumped David Moyes' United side out of the League Cup on a penalty shootout and beat them in the Premier League but prior to that it has been a fairly one sided affair in the head-to-head records.
United have won the previous six consecutive Premier League games and nine of the last 11 league meetings, with two draws in that time. Van Gaal will hope his side can kick start their Premier League challenge against an opposition they have had plenty of success against in recent years.
Rooney fired United back into the Swansea game and the new Manchester United captain will hope to extend his scoring run when United face Sunderland this weekend.
Pre-season has proved fruitful for the 28-year-old England international who notched five goals in the United States and against a Sunderland defence which leaked twice against West Bromwich Albion in their opening game of the season the price of Even Money (2.0) that's generally available looks to be a fair price.
Therefore the 9/2 (5.50) is a great opportunity for new Paddy Power customers to back an in-form Rooney to score anytime in Sunday's game at a price that is over three times what is generally available and as a result is bound to be extremely popular with punters.
Anyone without a Paddy Power account who wants to take advantage of these offers can sign up for one here.
