Liam Rosenior has declared he retains the complete backing of Chelsea's hierarchy, even as the club endures a barren run of four successive Premier League defeats.The 41-year-old, who took charge following Enzo Maresca's departure on New Year's Day, saw his side fall to Manchester United at Stamford Bridge on Saturday.That result has opened a seven-point gap between Chelsea and Liverpool in fifth position, placing the Blues' Champions League ambitions in serious jeopardy.When questioned about whether he still enjoys the confidence of those above him, Rosenior was unequivocal: "100 per cent. They've been supportive of me in our daily conversations, the sporting directors involved they've been magnificent in their support of me and the team."TRENDINGStoriesVideosYour SayThe head coach acknowledged that co-owner Behdad Eghbali had publicly expressed confidence in him last week, stating: "Of course, it's a results business, but we think he can be successful long term."Eghbali also indicated the club would pursue more seasoned players during the summer transfer window and would adjust their approach if necessary, having assembled the Premier League's youngest squad.Rosenior reflected on those remarks: "He wants consistent trophies and consistent success for this club. That's what we've spoken about in the now, in the summer and how we build."The manager added that everyone at the club understands what is required to restore Chelsea to their rightful standing.Following Saturday's defeat, footage circulated widely on social media showing defender Wesley Fofana apparently ignoring attempts by first-team coach Justin Walker to engage with him.Rosenior confirmed he had addressed the matter directly with the player and that Fofana would remain available for Tuesday evening's fixture at Brighton.LATEST SPORTS NEWS:Nike forced to take down Boston Marathon sign as offended athletes accuse them of 'pace shaming'Matt Fitzpatrick makes feelings clear on hostile American crowd after RBC Heritage winSnooker chiefs respond after Barry Hawkins complaint at World Championship"I've spoken to him about it and he's just disappointed that we're losing the game," said Rosenior."I do think he could have shown that emotion in a better way and that's something I've spoken to him about, but the optics are not the reality."The head coach emphasised that Fofana had apologised for his conduct, noting that young players will inevitably make errors.Chelsea will be without Estevao for the Brighton trip after the Brazilian sustained a hamstring problem during Saturday's match.Striker Joao Pedro is also a concern and will undergo a late assessment to determine his availability.There was more encouraging news regarding Levi Colwill, who has been sidelined with a long-term knee injury.The defender featured in a behind-closed-doors fixture on Friday as part of his recovery, though he is not yet ready for first-team action.Colwill is expected to gain further match fitness by turning out for Chelsea's Under-21 side this coming Saturday.As for Brighton, the Seagulls will go into the clash on the back of a dramatic 2-2 draw with Tottenham, having scored late to narrowly avoid defeat.
