Cape Town - David Moyes feels Papy Djilobodji's needless red card during Sunderland's 3-0 win over Hull is a sign of his inexperience.
After making a poor start to his Sunderland career after signing for the Black Cats from Chelsea in the off-season, the Senegal international has played a key role in their back-to-back wins in the Premier League
However, the 27-year-old undid much of the good work he had done in recent times when he was given his marching orders during the victory over Hull for a needless, clumsy challenge far from goal which rules him out of next week's match against Liverpool.
"I thought he played well again, he's coming on," Moyes said.
"But it just showed, he's 27 but he's playing like a 22 or 23-year-old centre-half at times with his little bit of inexperience.
"But it comes from games as well, and not maybe being brought up in the culture of ‘Don't always go tight all the time', we're 3-0 up, what are you going in for a challenge for when it's 3-0?"
With Djilobodji suspended, former Manchester United defender John O'Shea is likely to start in the heart of the Sunderland defense when they travel to Anfield for a clash against the Reds on Saturday.
The Black Cats moved off the foot off the table with their recent win over Hull City and are currently on eight points in the English Premiership, four points from safety.
Kick off is at 17:00.
