The 59-year-old has urged his men to create the perfect atmosphere to get the best out of the Barcelona star this summer
Argentina coach Alejandro Sabella has urged his side to create the right climate to allow Lionel Messi to flourish at this summer's World Cup.
Messi has faced criticism in recent weeks after falling below his usual extraordinary performance levels for Barcelona, notably in the Champions League quarter-final defeat to Atletico Madrid and the 2-1 loss to rivals Real Madrid in the Copa del Rey final.
Sabella is unperturbed by those criticisms, however, and is confident Messi can shine in front of the world audience when Brazil hosts the World Cup later this year, providing his team-mates provide the right assistance.
"Messi is fine but we must try to be the best possible team to help him," Sabella told reporters.
"We have to get the team to be more compact, occupy the spaces.
"Messi has matured as a person, he has interior peace, but we have to create a climate that will allow him to be happy, I think we have to let him be calm."
The 26-year-old has netted 39 goals in 42 appearances in all competitions for Barcelona this term.
Messi previously featured for Argentina at the 2006 and 2010 World Cups, but was unable to help the Albiceleste past the quarter-finals in both instances.
