A former Barcelona player believes the 28-year-old is now a more complete forward, capable of hurting teams with his ability to play the final pass
Carrasco believes it merely took time for the Argentina international to find his feet again after a long year that saw him reach the World Cup final with his country.
“In the moment he found himself good physically and mentally, he tried to bring the team together, everybody joined him and from there all talents became stronger,” said the 56-year-old.
“The god of football started playing, he is unstoppable when he starts playing. If you think otherwise, ask [Jerome] Boateng or all those fantastic players that face him.
“Barcelona expected good things last season, but not the treble. Matching the magical season of 2009 seemed almost impossible. Messi was the cornerstone of that success.”
Carrasco claimed 10 major trophies during more than 300 appearances for Barcelona, including the Liga title in 1985.
He also reached the final of the European Championship in 1984, where Spain were beaten by host nation France and the inspirational Michel Platini.
