Charlton have to strengthen in defence - Jones

Charlton Athletic head coach Nathan Jones said the club "have to" strengthen the squad in defence after seeing his side lose 3-1 at League Two Cambridge United in the Carabao Cup.

Jones made 11 changes to the team that lost to Leicester City at the weekend, which he said was necessary to ensure the Addicks could continue to compete in the Championship.

They have until 7pm on Monday, when the transfer window closes, to bring in defensive reinforcements.

Summer signings Charlie Kelman, Tanto Olaofe, Joe Rankin-Costello and Harvey Knibbs were all named in the starting XI, with Jones admitting after the game none of those who began the game had staked a claim to retain their place against Queens Park Rangers on Saturday.

When asked if the club would look to add to their backline, he told BBC Radio London: "We have to.

"We have to strengthen in that area of the pitch because if we don't strengthen then it only takes one or two [injuries] and we're exposed, and then with the greatest respect the Championship is different."

Ollie Hobden made his debut at right wing-back, with Keenan Gough also coming off the bench for his first appearance for the Addicks.

Ibrahim Fullah's long-range stunner was a rare high point on a night that saw Karoy Anderson shown a red card deep into stoppage time.

"We have to make sure we are considerably better than tonight and our levels are as good as they were on the weekend because we were outstanding on the weekend," said Jones.

"We've lost two back-to-back games and we don't often do that, and that's what I'm disappointed with.

"But I had to make those changes tonight because of the levels we'd had and what we have to do on Saturday and that's why we got what we deserved, because we were second best all over [the pitch]."
