Chelseas difficult season has been well documented, with the defending Premier League champions currently languishing in mid-table.After bowing out of the Champions League on Wednesday, Guus Hiddinks side are left with the FA Cup as their final chance to salvage silverware.The interim boss described the Blues as a team in transition after the defeat by Paris Saint-Germain, and with a change in manager expected at Stamford Bridge this summer, theres likely to be plenty of transfer activity too. So we asked Sky Sports Paul Merson which Chelsea players he would keep at the end of the season, and which he would move on ahead of next term... Guus Hiddink said Chelsea were a team with an uncertain future after their PSG defeat Who should stay and who should go? Paul Merson says... Stay Let go Wait and see Thibaut Courtois Eden Hazard Branislav Ivanovic Cesar Azpilicueta Oscar Gary Cahill Kenedy Pedro Kurt Zouma Loic Remy Cesc Fabregas John Obi Mikel Nemanja Matic Baba Rahman Willian Diego Costa Bertrand Traore I wouldnt necessarily say Chelsea are in transition, but they need to buy a lot of players. You look at McDonalds - they sell more cheeseburgers, more fries, and more soft drinks than any other fast-food chain in the world, but they still do adverts.Chelsea won the league last season, but they didnt invest to keep them on top, and we saw the same problem a couple of years ago with Man City. You have to keep kicking on, and sometimes you have to upset players by bringing in others who are better.Goalkeeper and defenceLooking at their squad, youd keep the goalkeeper no question. Thibaut Courtois is the undisputed number one.But I watched Baba Rahman the other week against Southampton and he was all over the place so Im not sure hes at the right level. I like Kenedy, hes a good young player and Id keep him at the club. Cesar Azpilicueta would be in-demand if Chelsea let him go, says Merson The way to look at it with Cesar Azpilicueta is, if Chelsea were to sell him, would top teams be in for him? They would be, so he should stay.Moving onto central defence, John Terry leaving still shocks me because hes the main defender at the club.Branislav Ivanovic has been poor this season and hes very fortunate to still be playing in the team. He was the best defender in the country last year but his confidence has dropped, and you see that happen to the best players.With him, Id wait and see how he plays over the first three or four games of next season and then make a decision very quickly. If he comes back and hes playing at his top level again, theres still a place for him. But if not, hed have to go straight away for them to win trophies. Branislav Ivanovic has struggled to live up to his performances from last season Im not the biggest fan of Kurt Zouma in the world. Hes quick across the ground but hes a bit rash. Hes still learning the game but Chelsea dont have time for that, they need to win things. Youd still keep him, though.If theyre getting rid of Terry they have to buy a replacement in the summer, but whos about? You only have to look at Manchester Citys signing of Eliaquim Mangala. He was the best part of £30m and youre not getting a lot for your money.That is what worries me with Terry, because they can spend £20m or £30m but theyre not necessarily going to improve. With Gary Cahill and Zouma at the back, for me theyre not winning the Premier League next season.MidfieldIn midfield, Cesc Fabregas would get a club tomorrow morning. On his day hes brilliant, and since Jose Mourinho has gone hes decided to play. Against Southampton he was absolutely outstanding, and hes got that in his locker so keep him. Merse believes Fabregas is one that Chelsea should definitely look to keep But would John Obi Mikel get a football match if Hiddink wasnt the manager? And how many top teams would put him in their side? I know hes done well since hes come in, but if youre looking to win the league I dont think you do it with Mikel playing 35 or 36 games.Nemanja Matic is a strange one. He was one of the best holding midfielders in the world last season, but hes dipped, along with everybody else in the squad apart from Willian. Id keep him because of what he showed the previous year, but I think Mikel could be on his way. John Obi Mikel has come back into the starting XI on a regular basis under Guus Hiddink Then you get to Pedro, and it just shows you how good playing for Barcelona can make you look. Hes had one or two decent games since he joined Chelsea but if I could get money back for him I would.Willian has been the best player at the club by a million miles this season. Hes been very good and all day long he should stay. Hazard in a rut? Eden Hazard struggles while Diego Costa thrives under Hiddink But Id drop Eden Hazard off if I could get £60m for him. Hes had one good year and this season hes been bordering on atrocious. If you can get the money, youd take it all day long. You dont know if he will turn out to be a one-season wonder and you cant take that chance. Eden Hazard should be sold if Chelsea can get big money, says Merse It just shows you why Ryan Giggs is held in such high regard, because he was so good for so long. His whole career he was eight out of 10. It wasnt nine out of 10 one year and then down to five out of 10 the next. Willian has been one of Chelseas best players this campaign Oscar is in and out. One minute hes in the team and looks great, and then hes out of his depth and lightweight. Id get rid of him if you can get good money.Strikers Diego Costa has found his top form under Guus Hiddink Diego Costa has started to perform now and he looks a proper player. For 60 minutes against PSG he had them in his pocket. He looked the player we thought he would be, and he wasnt worried about beating people up. Strikers like that dont come around too often and you have to keep hold of them.Loic Remy should be gone, and youd keep Bertrand Traore because hes one for the future, but they would need to buy another forward in the summer because it cant just be Costa.Also See:Chelsea face transitionHazard stuck in a rut?Where would Zlatan fit in?Weekend football questionsWholesale Authentic Hockye Jerseys .
