The Croatian was caught on camera ... as was Adrian.

Spirits are high at West Ham United at the moment. The team is playing well under Slaven Bilic and the results are following.
It seems that a training ground game between yellow bibs and blue bibs came out with the yellow team winning.
The likes of Mark Noble, Carl Jenkinson, Dimitri Payet and Andy Carroll then posed for the cameras as victorious team-mates - but not before Croatian striker Jelavic feigned to shoot at the group, who shuddered in typical fashion.
Adrian was not so kind. He decided to actually kick the ball at his team-mates - hitting Jenkinson in the back of the leg.
All that larking about is certainly good for morale and hopefully West Ham can carry that momentum into their clash with Crystal Palace on Saturday.
