Zlatan Ibrahimovic and Cristiano Ronaldo were involved in an amusing Twitter exchange on Wednesday following a birthday message sent by the Swede to the Portuguese on the social networking site. The Sweden striker pledged to send the Portuguese one of his personalised jerseys as a birthday present, provoking an amusing riposte from the Real Madrid man. Ronaldo played 90 minutes for Real Madrid in their 3-0 derby win over Atletico in the first leg of the sides' Copa del Rey semi-final on Wednesday.
