Gazzetta dello Sport says Inter have accepted a bid of €27 million from the Russians for Eto'o.
Inter will benefit from the 12m per season wages saved until 2014, the date his contract was set to expire.
Including taxes, that figure is doubled for accounting purposes, so becomes 24m per season for three years. In total, that's €72 million saved in wages, plus the fee, which comes to €99 million.
"Thank you to everyone. I will always support Inter and ask just one thing - win even without me," Eto'o told teammates over the weekend.
