Newcastle defender Haidara looks set to sit on the sidelines after suffering an injury.
With Paul Dummett still out of action, this means Steve McClaren will have to face the next couple of weeks without a natural left-back, building a makeshift defence from a side who have shown little of their ability to defend this season.
The Haidara injury will also go to reveal the biggest mistake McClaren made over the summer, when he opted against signing another left-back during the transfer window.
Dummett is well known for his injury issues, meaning he will only ever be playing a bit-part role, despite his talents.
On the other hand, Haidara is consistent, but has yet to show he is of the quality needed to be a Premier League defender.
He should not have started the season as first-choice in McClaren’s set-up, and the head coach should have made it one of his transfer priorities to sign a new, top quality left-back over the summer.
With the players brought in, Newcastle proved that they still have a buying power over other European countries, and they have both the finances and reputation to sign top quality players.
Yet McClaren opted against signing another left-back, knowing that Haidara would be playing the majority of games this season.
Now that the 22-year-old is out of action, the head coach will have to look at alternate options in his squad, but he would have had cover if only McClaren decided to sign another left-back during the summer.
