Tottenham boss Mauricio Pochettino is backing Juan Cuadrado for success with Chelsea.
Spurs were due to face Cuadrado for their Europa League knockout tie with Fiorentina.
"He is a top player," said Pochettino.
"He is a decisive player. He is very strong. I've watched him a lot playing for Colombia, his national team. (Jose) Pekerman and Nestor Lorenzo, the manager and assistant manager for Colombia, are my friends. I speak always about Cuadrado. He is a top player."
