Ahmed Musa started from the bench but was called upon on the 35th minute when Leonardo Ulloa injured his thigh. Musa grabbed the opportunity with both hands and delivered a man of the match performance.
Musa, a £17m acquisition from CSKA Moscow in the summer had seen little of the action since arriving at the King Power stadium, in fact his last goal for the club was in October 29.
Everton went ahead in the 63rd minute through Romelu Lukaku.
Three minutes later, Ahmed Musa equalized for the foxes and before Everton could react, Musa doubled his tally in the 71st minute to give Leicester City a well deserved lead and victory at end of 90 minutes.
His manager Claudio Raneri was very happy with him and he said ‘ I’m very pleased with our performance and it is important for Musa – he is more confident now’. ‘We wanted to win and go through in the FA Cup. It’s an important competition and more because we lost against Everton at home so we wanted revenge.’
