Real Madrid right-back Alvaro Arbeloa fell out of favour at Real Madrid last season as Daniel Carvajal staked his claim to the spot.
So with the Spaniard trying to reclaim a spot in Madrid's regular XI, he did quite possibly the worst thing possible to better his case: He attempted an extremely foolish tackle in training in James Rodriguez's direction.
The same Rodriguez whom Real Madrid shelled out a fortune for earlier in the summer and expected to be one of their key schemers.
Rodriguez avoided the tackle and was unscathed, but matters could have been exponentially worse, and Arbeloa's studs-up challenge clattered Rodriguez.
