Which is the sensible option.But say he wants £5k a week which is rumoured what he was on here. The best offer has been £3.5k to which he's rejected. He's had no income since the end of July now that's nearly 15 weeks or £15k. If he waits it out much longer than the total he ends up with for the year is going to be less than if he'd taken the £3.5k at the start of the window.
Like I said, without tarnishing all with the same brush, from my experience agents lower down the football pyramid aren't renowned for being too bright. To make matters worse they're becoming far younger and less experienced. Meaning that the above logic you aptly applied to the situation may not be replicated in the minds of a young hungry football agent chasing his or her next big commission.
Players rarely make a habit of interfering with the salary negotiation process too as that's essentially the whole purpose of employing an agent - which is another issue in my opinion. Agents are essentially given the keys to handle all contractual negotiations, whilst acting as a representative/intermediary to their player. So, as with most players, it's likely that Hiwula's financial situation isn't dictated by himself whatsoever. This is where agents can be especially dangerous, as far too much trust is placed in their hands. Many are guilty of chasing lucrative contracts rather than having due consideration of what's actually best for their player.
