New Chelsea boss Guus Hiddink has hailed striker Diego Costa after he scored twice in their 2-2 draw against Watford on Boxing day.
It was the Dutchman's first game in charge since returning to the club after the sacking of Jose Mourinho.
The game saw Costa pick up his fifth yellow card of the campaign in the Premier League, meaning he will miss the Blues’ next tie against Manchester United at Old Trafford.
‘He focused on what he’s good at and he’s very dangerous, that’s important, not wasting extra energy where you shouldn’t. He did that with two goals perfectly," Hiddink said, chelseafc.com reported.
‘He’s out (on Monday) which means we have to think how to solve that problem. It’s a pity after a good performance, we have to solve that in 48 hours.
‘Don’t overestimate the influence of managers. You try to give people focus. Sometimes you go into training and tell them to focus on what they have to do, you do that in meetings and training sessions. When everyone knows what he's capable of, and knows what trap he must not go into, whether it’s caused by yourself or somebody else, then you focus on your job. He showed that today with two terrific goals.’
