Real Madrid president Ramon Calderon has tried to improve relations with Milan, after the Italian club’s vice-president Adriano Galliani launched a verbal attack on them in a Spanish newspaper.

“We have read with great surprise the interview you gave to sports daily Marca,” Calderon said in an open letter to Galliani on the Primera Liga club’s website.

“We are absolutely sure that this is down to a dreadful misunderstanding between our clubs.

“We are writing this letter in the hope that we can restore cordial relations between these two great clubs as soon as possible.”

Galliani was highly critical of Calderon and his sports director Predrag Mijatovic over their efforts to persuade Milan’s Brazilian midfielder Kaka to join Real, and said: “Milan declares war on Real.”

During his campaign to be president Calderon claimed he had an agreement from Kaka to join Real, athough the Brazilian has subsequently denied this, and signed a new, improved contract with Milan.
