Chris Hughton may have two additional injury concerns for their next visit to Manchester to play at the Etihad against Manchester City this Saturday.
Despite making eight changes from last weekend, Hughton lost Robert Snodgrass to concussion after a nasty clash of heads with Rafael in the second half and Nathan Redmond limped off after straining a muscle.
“Robert’s gone to a local hospital as a precaution – he was out cold for a short period of time. He’s got concussion and will be under observation overnight.
“They will X-ray him to make sure nothing’s broken. By the time he was on his way off the pitch he was aware of what was happening around him.
“Nathan strained a muscle just above his hip. It’s quite painful to start with so there was no way he could continue. We will just have to see how he recovers over the next couple of days.
Hughton paid respects to United’s performance during their Capital One Cup victory but insisted that luck wasn’t with them when United opened the scoring with a penalty.
“I thought the first half our perfofrmance could have been better, in the first half we were given a penalty against us which was incredibly soft and not a penalty.
“A penalty as soft as that gives man utd a lift and deflates you.
“When you come to stadium like Old Trafford and club like Man United you need to get the decisions right and get every bit of help you can.
“If the referee deems there was contact then it’s a penalty but we’ve had five situations like that this season when a penalty wasn’t given. The players didn’t think it was a penalty either.
“We were able to limit United’s clear cut chances but they were very clinical with the chances they did get.”
