Leicester City fans called for the sacking of boss Russell Martin during Saturday’s thumping 4-0 defeat to Oxford.The Foxes were comfortably swept aside by Aaron Ramsey’s side at the King Power Stadium to hand them their heaviest loss in England’s third-tier.Martin was targeted by the home support in Leicester’s 4-0 defeat at home to OxfordGettyA double from Mark Harris and goals from Mo Missanga and Jamie McDonnell condemned Leicester to their second league defeat of the season after five games played.The manner of the goals conceded appeared to anger the fans most.Leicester’s failure to show any improvement after the interval, having gone into the break 1-0 down, sparked anger from the stands with Martin the main target.What were Leicester fans chanting about Russell Martin?Sections of the King Power Stadium were heard chanting: “Russell Martin, you’re football is s***.”Fans were reacting to Martin’s preferred possession-dominant football inspired by Pep Guardiola’s philosophy.Question marks have been raised around whether the imposed style is the right fit for League One football or the standard of players at Martin’s disposal.Oxford fans even got in on the act, chanting, ‘You’re getting sacked in the morning,’ to which Leicester fans joined in and continued the chant.Fans were seen flocking to the exit when Oxford scored their third goal in the 60th minute.And before they left, there was also a message for Leicester’s board spearheaded by King Power CEO, Aiyawatt Srivaddhanaprabha, who was in attendance for the match.Fans vigorously shouted, ‘Sack the board,’ as disgruntlement echoed around the stadium.Leicester City owner Aiyawatt Srivaddhanaprabha was also targeted by angry fansGettyLeicester, who beat Plymouth Argyle earlier in the week, are reportedly up for sale – a decade on from their fairytale Premier League title success.However, for some fans, that sale can’t come quickly enough with the Foxes deep in the mire.With Profit and Sustainability sanctions a thing of the past, the Midlands club were expected to mount a League One promotion challenge this season.Martin was drafted in to lead the Foxes into a new era, but just four weeks into the new campaign, there is little evidence of a renaissance.Leicester find themselves in 17th place and already seven points adrift of leaders Sheffield Wednesday.There was an air of pessimism among the fanbase following Martin’s appointment in June.Russell has won just one of his five League One games in charge of LeicesterGettyThe 40-year-old signed a three-year contract signalling King Power’s long-term backing for him and his backroom team.There is little to suggest that the board could wield the axe on him so soon after his arrival, but it appears that Martin is already losing sections of the club’s support.Martin lasted just 123 days as Rangers boss last season, becoming the club’s shortest-reigning manager in history.Prior to his spell north of the border, he led Southampton to promotion to the Premier League through the play-offs, but was sacked the following season after securing just one win in 16 Premier League matches.Speaking on GameDay Live with Adrian Durham, Leicester legend Christian Fuchs was asked about the 4-0 defeat to Oxford.What has Christian Fuchs said about Leicester?To which the Austrian, who didn’t watch the full 90 minutes, said: “It’s painful, we’ve seen the goals coming in, we kept track of it and I actually couldn’t believe it.Fuchs, who won the Premier League with Leicester, admits the club’s form is painfulGetty“I was hoping that after the last game, after the win [over Plymouth], that things will go now into the right direction, but this is something that really pains me, to be honest.“I’ve looked at the stats right away after the game, and it doesn’t look like it was a 4-0, that Leicester was in charge of the game, but it’s those specific moments that are costly.“For me to really give my opinion, I would need to see the game, but definitely from the outside, it doesn’t look good.”Fuchs was then questioned whether Martin is already under pressure, leading him to say: “Yes.“At Leicester City, knowing the history of the club the last 15 years, going into this club, just being relegated, the expectations are to bounce back up right away again.”He concluded by remarking: “It’s definitely painful for me to see the final result today.”
