Meanwhile, Gordon Strachan has spoken highly of Leeds United on paddypower.com.
The former Leeds midfielder is impressed with how head coach Marcelo Bielsa’s side are doing in the Championship at the moment.
Strachan wrote about Leeds on Paddypower.com: “You beauty! Leeds United were great against Wigan. There energy is fantastic, the players are enjoying themselves.
“It’s amazing when, there’s not a big change in the squad, it’s just when players realising that running and closing down is a huge part of the game, they completely enjoy it.
“You get a kick from it, you think ‘wow, this is wonderful’. Add skill and ability, and you’ve got a great side.”
