BBC Chief football writer Phil McNulty has been answering your questions on all things Premier League.
Jim asked: Hi Phil, always enjoy reading your articles on BBC Sport. With all the fuss about the bad game Trent Alexander-Arnold had, is it being overlooked a little that on the other flank, Andy Robertson has really dropped off in recent months? Is it time for Liverpool to splash out on a new left back and if so, who?
Phil answered: I do think we need to be careful not to go into a knee-jerk about Trent Alexander-Arnold’s poor game on Sunday but there is no doubt the timing was not great after Real Madrid officially declared their interest.
He was so far off the pace and careless, and was clearly exploited by Manchester United, who launched 54% of their attacks down his right flank. His stray pass led to Lisandro Martinez’s first goal for United and Amad Diallo’s equaliser also came down his flank.
Unfortunately for him and Liverpool, this will become an issue and a talking point as long as his future remains unclear.
He can put it right quickly with good performances, but for the first time yesterday, I heard the noises of frustration from Liverpool fans towards him – not a huge number but enough to make themselves heard.
Liverpool do not need this to escalate when they have such a great chance of making this a wonderful season under Arne Slot.
Meanwhile, I agree about Andy Robertson. He has not been at his best this season and, while still a fine full-back, Liverpool will soon have to start looking to the future.
Wolves and Bournemouth fans won’t like this, but Rayan Ait-Nouri and Milos Kerkez are two players I can see them looking at. Sorry Wolves and Cherries.
