The win was secured by Michu's ninth and tenth Premier League goals, his arrival in such a cut-price deal going down as bargain of the season.
But he stopped short of speculating how many more he can add. The Dane said: "I'm very pleased with Michu, he's scored many goals and players who do that will always be a bargain whatever their price because goals make points and points give possibility to play at this level, that's why goals so important.
"I don't want to put any numbers on him because we know goalscorers have their moments where everything goes in and there are periods where they can struggle. But he is not just a goalscorer, he works very hard and plays in an important position for us and he is an important player for us."
