Zico laments impending Zhirkov loss
The 25-year-old, dubbed the 'Russian Ronaldinho' is reportedly due to arrive in London this week to seal a four-year deal with the Stamford Bridge outfit, with both Arsenal and Liverpool linked with the player in the past.
And former Brazil great Zico - who scored 52 international goals in just 72 outings for his country from 1976-88 - says it will be an impossible task attempting to replace the left-sided Russian international.
"Currently in football there is no player who is able to replace Zhirkov," he told Sport Express.
“Zhirkov to CSKA is like Cristiano Ronaldo to Manchester United or Kaka to AC Milan.
"As we know, both players moved to Real Madrid and I think their former clubs will be seriously concerned about how they will do in the future without their star players.
"Remember how Manchester looked last season when Cristiano Ronaldo was missing. The attack of the team looked much weaker."
