Hodgson has been in charge of England since 2012, yet his tenure has been one of mixed fortunes thus far as impressive qualifying campaigns have been met with poor major tournament results.
England’s latest 0-0 draw with Slovakia sees Hodgson’s men qualify from Group B in second place with five points, with rivals Wales topping the group after they impressively defeated Russia 3-0.
Question marks have been raised following just the one win in three thus far at Euro 2016, and Merson believes England must now go all the way for Hodgson to keep his job.
“If Roy doesn’t win this tournament, he needs to go. They’re already talking about his contract and what would rank as a successful tournament. But he hasn’t impressed me at all,” Merson told the Daily Star.
“I thought he was poor against Wales and I nearly fell out of bed when I saw the headlines about him being a gambler. We were playing one up front against three centre backs, and Kane was getting isolated.”
“There are no other outstanding teams yet and England will be there or thereabouts. Their confidence is high. Roy just has to make sure he gets it right.”
Under Hodgson, England have won just three of 10 major tournament games and one of the last six following their disappointing show at the World Cup 2014 in Brazil.
England’s failure to beat Slovakia means the Three Lions have been placed in the second half of the knockout rounds alongside France, Italy and potentially Germany if they win Group C.
Should both England and hosts France win their first knockout matches, they will meet in the quarter-finals at the Stade de France in what would be a fascinating encounter.
