Barcelona midfielder Cesc Fabregas was surprised by Juan Mata's move to Manchester United.
United were interested in Cesc before signing the former Chelsea star.
"I was surprised to see Juan move there because I think he has been Chelsea's best player over the last two years," said Fabregas.
"He's produced some amazing performances as they won the Champions League, Europa League and FA Cup and he scored in the final of the European Championship with Spain."
