Barcelona star Lionel Messi said that his partnership with Zlatan Ibrahimovic is still a work in progress. Ibrahimovic joined Barca from Inter Milan this summer, replacing Samuel Eto'o, who formed a lethal strike force with Messi and Thierry Henry last term. Following the 2-0 Champions League victory over Dinamo Kiev on Tuesday, Messi implied that El Tricampeon still have a lot to give. "As far as Zlatan and I go we are only just starting our partnership," the Argentine ace told UEFA.com. "It's the beginning of the season and we are just getting to know each other. "We have the feeling that our understanding is improving with every game and we hope that pattern continues."
