The 23-year-old is frustrated by a recent change in Chelsea’s tactics under head coach Liam Rosenior, according to The Sun. Palmer reportedly feels these structural adjustments have denied him the necessary space on the pitch to influence games as he did during his debut campaign in west London. Further adding to his unhappiness is the departure of Nicolas Jackson, who joined Bayern Munich on a season-long loan in September, as their play styles were compatible on the pitch. With Jackson gone and Chelsea bringing in Joao Pedro and Liam Delap, the chemistry in the final third has struggled to replicate last season's heights.
