Chelsea boss Mourinho excited by what he's seeing from Diego Costa
While only a friendly it was hard not to be drawn to the all-round quality of the £32 million signing from Atletico Madrid.
"He's very intelligent the way he presses and he's a team man," said the Chelsea chief.
"He had two big chances to score but he prefers not to risk, but played for the team. We can feel he's happy to be with us and we're very happy with it."
