Argentina captain Lionel Messi has urged his compatriots to be realistic in their World Cup expectations, warning that other teams heading to Russia are better. In an interview with Argentine Canal 13, Messi also discussed why he did not take the chance to play for Spain and said that Barcelona will be his only European club. "People need to know that we are not going to Russia as favourites but we have a group of very good players and we are ready to scrap," Messi said.
