Liverpool retook the lead at the top of the Premier League table after defeating Cardiff 4-1 on Saturday afternoon.Mohamed Salah opened the scoring after just 10 minutes, before a second half brace from Sadio Mane and a first Liverpool goal for Xherdan Shaqiri gave the Reds a comfortable victory.Jurgen Klopp was happy with his side's performance but did admit that there was room for improvement."Very good moments, a lot of very good moments and of course periods where we could’ve done better, that’s how it is," he commented after the game, per Liverpoolfc.com."But we played Wednesday, we played today, we had to create and to create and to create and to create - that’s really hard work, to be honest, and that makes it so difficult."We could’ve done, of course, better in a few moments."Although Liverpool would have been happy with the three points, they would not have been too happy with the goal they conceded.Callum Paterson's goal 13 minutes from time ended Liverpool's record of keeping a clean sheet at Anfield in every league match since February - a total of 918 minutes.Alberto Moreno was widely criticised for his part in the goal but it seems one particular Liverpool fan actually pinned the blame on Alisson Becker.Alisson has been superb since joining Liverpool in a £66.8 million deal earlier this summer.He has conceded just seven goals in 13 games so far for the club and has been a reassuring presence between the sticks.The vast majority of Liverpool fans have quickly taken to the Brazilian goalkeeper but it seems not everyone is happy with his performances.Twitter user @EdwingTellezD, a Liverpool fan, actually tweeted Alisson directly that he was not good enough following the Cardiff game and that he should leave the club.Writing in Portugese, his tweet translates roughly to: "You are not at the level of the Reds! Better now or get out!"And after Liverpool fans came to Alisson's defence, he shut down his critic with a brutal tweet.The Liverpool stopper wrote: "Did you see the size of your rejection, you idiot?! @YNWA"

That was not the end of the argument, however.

The fan replied: "I'm a Red and it doesn't matter if you and your followers call me an idiot and they offend me, I never walk alone. What you have to say is in the field. Be worthy of that shirt, even now it's not."

And Alisson felt he had to reply again, writing: "It seems your opinion is unique."

Alisson completely shut down his critic with that first tweet and Liverpool fans could not get enough of how he dealt with the situation.
