Former England and Everton boss Sam Allardyce has emerged as the shock favourite to become Leeds United boss following their struggles.  According to a report by Sportsmail, the Yorkshire side are set to sack struggling Javi Garcia on Tuesday and will bring Allardyce in as an immediate replacement.  The former Bolton manager is expected to start on Wednesday to keep the club in the Premier League. Leeds United have begun the process of restructuring the club and have already sacked Sporting Director Victor Orta. They currently sit inside the relegation zone and see Allardyce as the manager to keep them above the murky waters.

The Englishman is one of the most experienced coaches in the game, having managed 13 different clubs. His first two games will be against Manchester City and Newcastle, two sides in the top four. So it will be daunting for Allardyce, who will be desperate to keep his solid record as a relegation specialist. Meanwhile, Sky Sports pundit Jamie Carragher has backed the 68-year-old to help Leeds avoid the drop this season. Speaking on Monday Night Football, Carragher was asked what he thought of Leeds United hiring Allardyce the former Liverpool defender said;  “Well, Sean Dyche is a similar sort of manager, and he’s come in at Everton to do that job of making them better defensively.  “We know in the past Sam Allardyce has done that job before. “I don’t think he’s ever come this late. I think he’s normally come in [and] had a January transfer window.  “He can bring his own players in and have that time to change it. But I think it’s probably a decent appointment. Whether the crowd will get behind that, I’m not so sure.  “I don’t know how Leeds supporters would react to Allardyce. But in terms of  trying to make them more solid, better defensively, there’s probably no one better out there.”
