Chelsea striker Didier Drogba believes that Luiz Felipe Scolari's sacking was the turning point in both his and the Blues' season.The 31-year-old has scored 11 goals from 19 starts in all competitions this season, eight of which have come after the Brazilian was dismissed at the start of February.The Ivory Coast international struggled with injuries at the start of the campaign but even when fit the former Portugal boss appeared to prefer Nicolas Anelka upfront.The burly frontman has responded emphatically to new manager Guus Hiddink's methods and admits that his experiences at the beginning of the season have made him hungrier to succeed."I really missed playing earlier in the season and now I am really hungry to perform," he told the Evening Standard."Scolari leaving made a big difference to me and the team. I was given a chance to show I was not injured any more and that I was ready to help the team."Drogba now has his sights set on Arsenal as the two London clubs lock horns for a FA Cup semi-final showdown at Wembley on Saturday.The former Marseille ace warmed up for the clash by tormenting Liverpool's defence in the second-half of the epic 4-4 UEFA Champions League quarter-final draw at Stamford Bridge in midweek and the player insists his desire is as strong as ever."I have my energy back," he added."The last two months my desire to play and win games has been very strong."
