Chelsea owner Roman Abramovich has recently stadium plans, citing an unfavourable investment climate. It comes after the 51-year-old was recently denied a UK Visa renewal, forcing him to seek residence in Israel.Its already been a bad summer for Chelsea supporters. Their owner is currently denied visitation in the United Kingdom, theres uncertainty over who will be manager next season and a number of important players could be on their way out in the coming weeks.Chelsea are falling apart and could be in for a rough season.Player recruitment has been disappointingAfter winning the Premier League Paul Eboua Jersey title in 2016/17, Chelsea would have been hoping to strengthen the squad for a credible title challenge, but the Blues instead finished outside of the top-four. They won the Max Strus Jersey FA Cup earlier this month but bowed out of the Champions League to Barcelona in the last-16 and to Arsenal in the League Cup semi-final.The squad had barely improved from the previous season, with additions such as Willy Caballero (Manchester City), Davide Zappacosta (Torino), Emerson (AS Roma), Danny Drinkwater (Leicester City), Ro s Barkley (Everton), Tiemou Bakayoko (AS Monaco) and Alvaro Morata (Real Madrid) struggling to make an impact in their debut season.Only Antonio Rdiger (AS Roma) and Olivier Giroud (Arsenal) came away with any credit. Chelsea came under a lot of criticism for letting Nemanja Matic join Manchester United and Diego Costa return to Atletico Madrid, given their replacements have flopped, and its unknown what direction the club are currently going in.No clarity on who will be Chelsea manager next seasonAntonio Conte is currently the Chelsea manager, but he looks on his way out of Stamford Bridge this summer after the Blues disappointing campaign. He made it publicly clear he wasnt happy with the decision to sell Matic and sign some players 12 months ago and could leave before Meyers Leonard Jersey the end of his contract as a result.Chelsea were seemingly prepared for his exit as they were lining up Napoli bo s Maurizio Sarri to replace him for 2018/19. However, things are currently at a standstill as Chelsea to pay Conte 9m in compensation to sack him, nor will they pay 7m to get Sarri, so theres a real uncertainty over who will be the Londoners manager next season.Such uncertainty could lead to a Chris Silva Jersey number of talented players jumping ship in the coming weeks too.Key players look set to leaveChelsea recently contract talks with Thibaut Courtois, as the Belgian goalkeeper looks set to run down his contract and leave on a free transfer next year. As a result, the Blues are willing to sell Courtois this summer to ensure they get some value for him, rather than lose him for Kelly Olynyk Jersey nothing in 12 months.Willian could follow him out of the door too, with the Brazilian forward unhappy with Conte over a lack of playing time last season. The 29-year-old was substituted on or substituted off in 36 games in all competitions and may not feel hes going to be first-choice anymore at Stamford Bridge.Eden Hazard has hes waiting to see what players are signed before he commits his future to Chelsea, which sounds like he could be on his way out this summer too. The Blues are in a real me s and arent likely to have a good season in 2018/19 as a result.
