Liverpool made Premier League history by scoring their fourth late winner as they ended Burnley‘s 24-game unbeaten home league run, while underlining that this team still needs time to click.With the help of our partners at FotMob, we look at Liverpool achieving a Premier League first and the concerns with their forward line.For the fourth game in a row to start their title defence, Arne Slot‘s men have needed a winning goal at the death to snatch victory – a wretched time for anyone hoping they’d drop points!They become the first side in Premier League history to win four matches in a row with a winning goal in the final 10 minutes or later.You cannot say it was not deserved, either, even if the complete performance lacked any eye-catching sequences as Liverpool sought to unpick the lock that was Burnley‘s 11-man defensive block.In the second half alone, Liverpool touched the ball 41 times in Burnley‘s box and didn’t allow the home side a single one, while playing 243 passes in the opposition half to their 16.Slot’s side ultimately forced Burnley into a careless mistake by continuing to ask questions, and Mohamed Salah was on hand to punish them and equal the longest winning streak Liverpool set across the league last season (four wins).That is not to say that all is operating as it should for Liverpool, with the attack showing it needs time to click.There is something to be said for the emotional release that a late winner offers, but we all know it is not sustainable for an entire season, and it means Liverpool’s attack needs to click.Against Burnley, Liverpool had 26 attempts on goal before Salah scored from the spot, and only three hit the target for a shot accuracy of just 11.54 percent – Burnley themselves blocked 12!Cody Gakpo had five shots (none on target), Hugo Ekitike had two (none on target), and Salah’s only shot was his penalty, while Florian Wirtz created four chances (second-most) and had three shots (none on target).They are concerning numbers, even if Burnley were pitching up tents in their defensive third, and despite the win, it highlighted the obvious early weakness for Liverpool.It’s a new-look combination up top, and Salah admitted earlier this month that he had yet to “figure the connections out yet” as he knew where “to find” Darwin Nunez, Luis Diaz or Diogo Jota.Those connections take time and banking three points while they are formed is a dream outcome for Slot, but the attack needs impetus, more complete performances and fewer potshots.Alexander Isak will add another new profile for the team to adjust to, and that means it could take a while for things to finally click, but there can be nothing but optimism that it will.Atletico Madrid will come to Anfield with similar frustrating tactics as Burnley, and it would not be a bad time for Liverpool to offer a glimpse at what a fully-functioning forward line could look like.* FotMob is an essential app for every fan to keep up to date with their team or follow football worldwide, with endless stats and features that offer all you could ever want and never knew you needed!You can download the FotMob App here.
