News'We know we need to still lift our levels of performance'
Andy Robertson acknowledged the Liverpool squad's need and desire to improve performances despite an 11-game unbeaten run.
The Reds extended their current streak without defeat by beating League One outfit Barnsley at Anfield in the Emirates FA Cup on Monday night.
Six wins, five draws and five clean sheets have been registered amid that form, though Robertson stressed the quality of overall displays has to be lifted.
"Yes and no," the vice-captain replied when asked about feeling the positives of going unbeaten, speaking to reporters after the victory against Barnsley.
"I think some of the performances still have to be better.
"Within that obviously you've got [moments where] you throw it away, you've got a draw against Leeds at home, a draw against Sunderland at home - games that you are probably expected to win.
"But within that as well you've obviously got a draw at the Emirates, you've got a win at the San Siro - games that weren't easy.
"So, I think yes and no. Obviously 11 unbeaten is good, we kind of stopped the bad form, which is always pleasing.
"But we need to still lift our levels of performance, I think everyone knows that and that's what we're working towards."
Emphatic efforts from Dominik Szoboszlai and Jeremie Frimpong put Arne Slot's men in front during the first half versus Burnley.
An error by Szoboszlai gifted Adam Phillips a response for the visitors ahead of half-time, but substitutes Florian Wirtz and Hugo Ekitike scored late on to book a fourth-round home clash with Brighton & Hove Albion.
"I don't think the performance was overly great, I thought we showed moments of quality, which you always have to show," said Robertson.
"I thought the goals were really good obviously, individual quality. But we've got to play a lot better than that if we want to go further in this tournament.
"I thought Barnsley were good, showed up really well, played with confidence, had a clear idea and caused us a couple of problems, which is never great.
"I suppose that's the beauty of the cup. That's what people want to see back at home.
"It's just we don't want to see it and unfortunately we've probably seen it a little bit too much, but happy we're in the next round."
