Angel Di Maria starred in Paris Saint-Germain's 2-1 Champions League Round of 16 second leg triumph over Chelsea on Wednesday.
The Argentine winger, who was sold by Manchester United in the summer, was integral in his side's victory at Stamford Bridge as the French giants advanced to the quarter-finals of Europe's premier club competition.
Di Maria laid on a pinpoint assist for Zlatan Ibrahimovic's steadying 67th-minute goal and his all-round performance was not lost on PSG boss Blanc.
"Angel Di Maria gave Chelsea a problem from start to finish," he said.
"They never knew where he was, but we always knew where to find him with the ball."
