|MAN UNITED LATEST
The Spaniard started as a substitute during Giggs' debut as United's stand-in manager but came off the bench to score twice after Wayne Rooney had put last season's title winner two goals in front.
The interim boss admits that he lost sleep over his decision to leave out several high-profile players, including Adnan Januzaj and Marouane Fellaini, who both failed to make the matchday squad.
"That was a tough one, as it was leaving so many players out," Giggs told reporters. "[Mata] was disappointed [not to start] and I'd expect that. It would be strange if he wasn't but he just showed the class that he's got both as a player and as a professional.
"He put on a half-hour masterclass, he was brilliant and I was really happy for him because it's not easy because he's got a big price tag.
"To not start the game was disappointing for him and I'm really pleased that he came on and made such an impact."
