Part of the rationale for Xabi Alonso’s appointment at Chelsea is that his style of play does not require a full squad overhaul — but that does not mean it will be a quiet summer.They are not in the same position as last summer, with a ‘bomb squad’ of unwanted players to clear out, but not everyone on their books can expect meaningful minutes next year. There are 29 senior players listed in the first-team squad on the club website, plus several who are on loan or have signed pre-agreements to join this summer. Nobody is out of contract, so any exits are dependent on finding an interested party.So who is best placed for a significant role under Alonso, and who might be better served by a loan or permanent exit? The Athletic looks at the options in each position.GoalkeepersAfter opting against pursuing a deal for Mike Maignan last summer, Chelsea have stuck with Robert Sanchez as No 1 — bar a brief spell where Filip Jorgensen usurped him in March. Sanchez has not been immune to errors, but his shot-stopping has been key to Chelsea and Liam Rosenior’s exit relieves some of the questions about his ability on the ball. At a time when the team needs stability, keeping him as first-choice goalkeeper feels a less risky option than going into the market.Mike Penders’ impending arrival after his loan at Strasbourg has implications for the rest of the goalkeeping department. If Chelsea want the 20-year-old to begin integrating into the squad as Sanchez’s deputy, it might be wiser for Jorgensen — who had a horrible moment against PSG, but has overall improved across the season — to move on. Teddy Sharman-Lowe, who gained experience on loan at Bolton Wanderers in the first half of the season, would appear to be next in the pecking order ahead of Gaga Slonina.Keep: Sanchez, Penders, Sharman-Lowe
