SIR Alex Ferguson has admitted he has not yet decided who will step into Cristiano Ronaldo's boots when it comes to taking penalties and free-kicks. Brazilian midfielder Anderson gave his boss a hint when he scored a cracking set-pice goal against Boca Juniors on Wednesday and Ferguson admits he is an option. "I have been thinking about this for two weeks now and I have no definite answer to it," Ferguson said. "I think it depends on what 11 players are playing in a particular game. I think we have two or three players who are natural to take responsibility. "(Patrice) Evra, (Michael) Carrick, Anderson and (Ryan) Giggs are all natural choices to take penalty kicks, but when I choose my 11 on a particular day, then I will make my mind up on that day." The chances are Anderson will be figuring more often this season following Ronaldo's departure. Ferguson says he, as well as Nani, has the "right platform and right training environment" and that the 2009-10 season could be when they come of age. "They are young and when you are young and have the ambition, then that can happen," said the Scot. "I expect to see that improvement and have no fears about Anderson and Nani. "They are young boys with young minds playing at the highest level of football." Who should take the free-kicks and penalties? Have your say.
