Guardiola warns Ibrahimovic over temper
The Swede, who moved to Barca from Inter Milan in the close season, protested a host of decisions in Barca's 1-1 La Liga draw at home to Villarreal on Saturday and was booked in the 88th minute for a reckless lunge at Diego Godin.
"He's a temperamental player and we need to be a bit careful because we might end up one day with 10 players," Guardiola said at a news conference.
"Ibrahimovic needs to be strong and he is capable of doing it as he's a great player," he added. "He can't control the referees' decisions."
