FC Barcelona, picture where is Arturo Vidal, and Real Madrid measure forces on Wednesday at the Camp Nou (17.00 hours in Chile) in the first leg of the semifin ales of the Copa del Rey, a first classic three almost followed, marked by the question of the presence of Lionel Messi, with discomfort, and to see if Real Madrid can continue with their State of grace in the eternal rival House. A duel where ‘King Arthur’ would begin, not to mediate any last-minute surprises, on the substitutes bench. Coach Ernesto Valverde continues with the policy of rotations in eleven and this time the former Juventus and Bayern Münich would be as an alternative. The precedent of the League Spanish, with the 5-1 seen without Leo Messi FC Barcelona at the Camp Nou and that precipitated the dismissal of Julen Lopetegui, is present in the environment, especially by the nerves that exist in the store blaugrana and who knows if in the White , by the fact that the argentino will be doubt until the last moment. Despite finishing the match against Valencia, with two goals that matched the 0-2 initial signing tables, Messi noticed discomfort, muscle overload. On Tuesday began training with his teammates, but their feelings, medical reports and eventually Valverde will mark its presence or absence in the first installment of the ‘Triclasico’. Jasper Cillessen, regular goalkeeper in the Copa del Rey and protagonist for his good performances will not be. An ill-timed muscle injury in the soleus muscle of his right leg, will prevent you play. Nelson Semedo, to stop Vinicius, perhaps one of the few new faces in the starting eleven on Wednesday. Whether or not Leo Messi, who has not scored yet against Real Madrid in the Copa del Rey, this first duel is expected intense and tight, as always, the incentive to have the place in the final game and see the best Real Madrid in this season with Karim Benzema to exercise at the end of the leader, challenge to a boat that is also sweet despite the draw against Valencia and whites have two points closer to eight. Since the copera end of 2014, when Madrid won at Mestalla (1-2) into the boat title, they have not become to see the faces in the competition. While the blaugrana are ‘Cups King’, lately the Madrid wins you the battle, as in ‘semis’ in 2013, the last precedent in these parts. Except any landslide of scandal as it has sometimes been, everything could be deferred for the return at the Santiago Bernabeu. For now, Barca will appeal to his domain of offensive game through the ball to take advantage, and Madrid will be guided by your good mood moment, daring to everything. However, Solari has doubts in the three lines of the field, once it has completely empty nursing, but its alignment might influence equally to any key parts also have fresh for the Derby on Saturday against Atletico Madrid. Probable lineups: FC BARCELONA: Ter Stegen; Semedo, Pique, Lenglet, Jordi Alba; Busquets, Rakitic, Arthur; Messi, Suarez and Coutinho. REAL MADRID: Keylor Navas; Carvajal Ramos, Varane, Marcelo; Modric, Casemiro, Kroos; Lucas Vázquez, Benzema and Vinicius.
