Diego Costa upset a few of his team-mates in Chelsea training (Picture: YouTube)

Chelsea star Diego Costa was looking particularly restless in training ahead of the side’s clash with Bournemouth at Dean Court this weekend. 

Costa’s form has dipped significantly in recent weeks, with him firing blanks in his last four matches for the Blues, and speculation surrounding the 28-year-old’s future has come to the fore once again.

The Spaniard was, of course, dropped from Chelsea’s squad which travelled to Leicester following a bust-up with Antonio Conte back in January and he appeared to upset a few of his team-mates in training this week.

Costa seemed to vent his recent frustrations during a training drill in Cobham, smashing up several hurdles which a member of Chelsea’s coaching staff had carefully laid out.

Some of Costa’s team-mates laughed off the incident but a number of them just watched on in utter bemusement – Eden Hazard, in particular, appeared annoyed by his bizarre antics.

The Spain international soon apologised after it was clear not all of his colleagues had found it funny.

Will Costa finally break his duck in front of goal away to the Cherries on Saturday evening?
