Manchester United host early relegation candidates Crystal Palace at Old Trafford looking to return to winning ways after last weekend’s derby defeat by City.
The Red Devils have never lost to the Eagles in the Premier League, winning eight and drawing two of their 10 encounters.
Louis van Gaal’s side are the heavy favourites to secure victory at odds of around 1/3 with most bookmakers.
City, meanwhile, travel to Queens Park Rangers looking to bounce back from their Champions League defeat by CSKA Moscow in midweek.
The Citizens are unbeaten in their last three meetings with the Hoops and are the heavy favourites to secure victory, at odds of around 8/15.
Backing both Manchester Clubs to win their games on Saturday would attract odds of around 2/1 with most bookmakers, so Paddy Power’s price boost to 11/2 is sure to tempt plenty of punters into a flutter before kick-off.
To qualify for the enhancement, simply open a Paddy Power account through this link and back your chosen result at the normal price on site. If your bet is a winner, your account will be topped up as per the terms and conditions set out here, and if your bet loses, your stake will be refunded as a free bet.
