Diego Costa must continue to fight and show his passion on the pitch according to his manager, Guus Hiddink, as reported by the Mirror.

The Spaniard caught the headlines after the two sides met at Stamford Bridge earlier in the season. Costa clashed with Arsenal defenders, Gabriel Paulista and Laurent Koscielny at the Bridge, resulting in the Brazilian being sent off after kicking out at the striker.

The Dutchman said:

I’d prefer to have players who, sometimes, you have to control or tell them ‘a little bit less’ than have to push them a bit.

Since Hiddink’s arrival, Costa has been in red hot form, however, at other times this season, it has seemed as if the striker has been more interested in picking fights with his opponents.

Hiddink believes many people can often overlook the striker’s attitude off the pitch:

Sometimes you are misjudged by images. But, off the pitch, Diego shows a lot of joy to everyone at the club. I observe the players when they are in the canteen, dealing with people who prepare the pitches, not snobby or arrogant… that’s good to see.

Hiddink added:

They are different characters off the pitch. On the pitch they have that desperate will to win, almost at any cost. That’s a slight change in character and behaviour.

As well as clashes on the pitch, the striker has clashed with his team-mate, Oscar in what was reported as a training ground bust-up.

The striker was thought to be a doubt for the game at The Emirates but he has overcome a shin injury.
