Palace would have no chance of signing Mason Mount, who has been as integral to Chelsea under Tuchel as he was under the club’s all-time record goalscorer.
But Lampard could go back for another of his former favourites, Kurt Zouma, who was the first-choice centre-back partner for Thiago Silva before Tuchel reinstated Antonio Rudiger and Andreas Christensen.
The sale of Zouma could raise around £30m, with Chelsea also expected to target a top-class centre-back this summer as they look to challenge for the Premier League title next term.
Meanwhile, Chelsea striker Batshuayi is currently on loan at Palace, with the Eagles having an option to buy as he enters the final year of his Stamford Bridge contract.
However, it is doubtful whether Lampard would look to keep him on after sending him out on loan to Selhurst Park in the first place – meaning Chelsea would have to offload the 27-year-old this summer or find another loan destination.
