Here are the best tweets:Mo Salah, was there ever any doubt Liverpool fans?4 - Mohamed Salah is the first ever @LFC player to score on the opening day of four consecutive league seasons; he's only the second to do so in the @premierleague for any club, after Teddy Sheringham (1992-93 to 1995-96).

Magic. pic.twitter.com/pI1YzYcywf— OptaJoe (@OptaJoe) September 12, 202050 – Mohamed Salah has scored 50 goals in 63 home games in the Premier League – only Alan Shearer (47 apps) reached 50 home goals in fewer appearances in the competition’s history. Phenomenal. pic.twitter.com/l1UJ23G7dP— OptaJoe (@OptaJoe) September 12, 2020What a start to life back in the Premier League for Leeds...3 - Leeds are the first promoted side to score 3+ goals away at the reigning champions in the Premier League since Hull lost 3-4 vs Man Utd in November 2008. Fearless. pic.twitter.com/6LRwOeRYui— OptaJoe (@OptaJoe) September 12, 2020It would have been special with the fans around...It’s such a shame that fans aren’t at Anfield for this. Would’ve been a serious spectacle.— FK ☕️ (@fkhanage) September 12, 2020Cause for concern for the title holders?Liverpool have conceded 3+ goals in back-to-back Premier League games at Anfield:⚽️⚽️⚽️ vs. Chelsea⚽️⚽️⚽️ vs. Leeds UnitedMarcelo Bielsa has been spying on Lampard's tactics again. 😉 pic.twitter.com/lFaDwj8dMv— Squawka Football (@Squawka) September 12, 2020Ohhh Virgil?2 - Virgil van Dijk has made two errors leading directly to a goal in his last four Premier League games, more than he registered in his first 154 appearances in the competition (1). Lapse. pic.twitter.com/4F1RSdEw2Y— OptaJoe (@OptaJoe) September 12, 2020Since the start of the 2018-19 season, no outfield player has made more errors leading to goals in the Premier League than Virgil van Dijk (3).😬 pic.twitter.com/CpMK1Ne1hh— Squawka Football (@Squawka) September 12, 2020Who would have thought that Lovren was the one making Van Dijk look good?— Paddy Power (@paddypower) September 12, 2020Not the best start to the season for the PFA Young Player of the YearTrent Alexander-Arnold was dribbled past three times in the first 45 minutes against Leeds United.The most he's been dribbled past in a single Premier League in his career is four times. 👀 pic.twitter.com/LvGsEpLFjt— Squawka Football (@Squawka) September 12, 2020Not many players made Trent Alexander-Arnold look that flat-footed last season. Brilliant from Harrison.— Daniel Storey (@danielstorey85) September 12, 2020Leeds playing with some heart...Leeds' Stuart Dallas made seven tackles in the first half, more than the entire Liverpool side combined.— Squawka Football (@Squawka) September 12, 2020What a game...That was genuinely the most entertaining half of the year. Yes, even in a year that had an 8-2 scoreline. Both teams playing well in attack and rusty at the back - makes for an unpredictable scoreline if they can retain that intensity in their first match of the season. #LIVLEE— Rohith Nair (@RohithNair) September 12, 2020
