David Luiz has admitted he had reservations about making the 'quick decision' to leave Chelsea for Arsenal on transfer deadline day in August.
The Brazilian's £8million move surprised supporters and divided opinion, but he felt compelled to take on a new challenge at the end of his Chelsea 'cycle'.
Luiz featured regularly under Maurizio Sarri, but new boss Frank Lampard arrived with a plan to promote more academy players to the first team, authorising the sale of the veteran defender hours before the window closed.
The centre-back had won Premier League, FA Cup and Europa League trophies during his second spell at Chelsea, and Luiz has revealed he had doubts about repeating his success at Arsenal.
