Chelsea are unhappy with Carlo Ancelotti's demands he be allowed to bring with him his AC Milan assistants to Stamford Bridge.
The Times says Chelsea are reluctant to recruit the Italian's trusted assistants, Mauro Tassotti and Filippo Galli.
The AC Milan manager remains Chelsea's first choice to take permanent charge in the summer, mainly as a result of the personal intervention of Roman Abramovich, the owner, but the club would prefer him to work alongside their existing coaching staff of Ray Wilkins and Paul Clement.
Chelsea want to promote a greater degree of continuity at a training ground that has seen wholesale changes over the past few years. José Mourinho's Portuguese and Brazilian coaching staff left the club with him and were replaced by Steve Clarke and Henk ten Cate, both of whom departed from the club last year. They were replaced by Luiz Felipe Scolari's Brazilian contingent, who were sacked along with the former manager in February.
