Arsenal boss Wenger: Abramovich has money to transform Chelsea
Wenger does not feel the regeneration of the squad will have a major impact on Abramovich's plans for continued progress.
"They have the financial potential to rebuild the team, which they are doing," the Arsenal manager said.
"They lost some historical players, like happened to us. It's difficult [to rebuild], but there is still a good cheque book.
"Chelsea have bought great players. They bought Luiz, they bought Hazard, they bought Mata."
Abramovich has a history of wasting no time in making changes at the top, with Roberto di Matteo removed earlier this season despite having won both the FA Cup and Champions League.
Wenger said: "They are so high on a financial planet that you can always get what you need."
