London, July 12 : Manchester United coach Sir Alex Ferguson has said that he ready to make life hell for his key striker from Portugal, Cristiano Ronaldo.

Incensed over Ronaldo's attempts to quit Manchester United for Real Madrid, Ferguson said he has not spoken to Ronaldo for the last two months and intends to continue giving him the cold shoulder until the club returns from their pre-season tour to South Africa on July 28.

Ferguson is reported to be keen on showing Ronaldo who is in charge by ordering him to return to Manchester after he checks in with the specialist on August 2, so he can be kept under the supervision of United's own medical team.

Ferguson is now planning to wreck any chance of Ronaldo featuring for Real in the Champions League next season by playing him as soon as he is fit in Europe, which would cup-tie Ronaldo and prevent Real from fielding him if he joins them.

United's pre-season preparations have been completely overshadowed by the saga surrounding the star.
