Jurgen Klopp's Liverpool took on Graham Potter's Chelsea at Anfield in what would have been a high-profile fixture in any other Premier League season. The two sides are among the most biggest teams in Europe, but have not enjoyed a great first half of the season so far.With Liverpool and Chelsea starting the game in 9th and 10th place respectively, there was less of a buzz around the fixture as there normally would be. Both sides have been plagued with injuries and have certainly underperformed this season.ESPN UK@ESPNUKLiverpool and Chelsea have gone over six hours playing against each other without either side scoring a goal 🙃5033381Liverpool and Chelsea have gone over six hours playing against each other without either side scoring a goal 🙃 https://t.co/XZOU7H91CZThe encounter saw both sides share points in a dull, goalless draw at the midway point of the Premier League season. Let's take a look at five talking points from the game.#5. Trent Alexander-Arnold needs to start for LiverpoolBrighton & Hove Albion v Liverpool FC - Premier LeagueJurgen Klopp opted to start James Milner at right-back for their home encounter against Chelsea. Trent Alexander-Arnold has been a mainstay in the position for several years and is widely considered one of the best right-backs in the world.The Englishman has several Premier League records to his name and is renowned for his attacking prowess from the right side of the field. He has been one of the Reds' most important players over the last few years and showed once again today why he deserves to start for the Anfield outfit.Despite playing just about 20 minutes, Trent Alexander-Arnold was in the thick of most of the action. He contributed to several attacks, even having a goalscoring opportunity himself.Although Alexander-Arnold has seen a dip in form in recent times, there is no doubt he has the quality that Liverpool need at the moment.#4. Mohamed Salah's form needs to improveWolverhampton Wanderers v Liverpool: Emirates FA Cup Third Round ReplayMohamed Salah has been one of Liverpool's most important players in the last few years.The Egyptian has arguably been their best signing in a long time and has contributed extensively to their recent success. Known for his pace and finishing ability, Salah is widely regarded as one of the best players in the world.The 30-year-old enjoyed a spectacular debut season in the Premier League and has carried his form into every season since. He has been extremely consistent for the Reds and is known for scoring on a regular basis, having won three Golden Boot awards.Salah has scored just seven Premier League goals so far this season, a number that is poor by his own standards. With Liverpool desperately looking for inspiration this season, Salah will need to step up to give Liverpool any chance of qualifying for the Champions League next season.#3. Cody Gakpo's finishing needs serious improvementWolverhampton Wanderers v Liverpool: Emirates FA Cup Third Round ReplayLiverpool announced the signing of Cody Gakpo for a reported £35 million just last month.Having impressed at club level in the last couple of seasons with PSV Eindhoven, Jurgen Klopp deemed him the right addition to Liverpool's squad in the winter window.Squawka@SquawkaCody Gakpo attempted more shots than any other player on the pitch in the first half vs. Chelsea...None of them hit the target. 🙃#LIVCHE20326Cody Gakpo attempted more shots than any other player on the pitch in the first half vs. Chelsea...None of them hit the target. 🙃#LIVCHE https://t.co/sR37zcjkkbGakpo is undoubtedly an extremely talented player and displayed his skills at the 2022 FIFA World Cup as well. He is blessed with pace, technical ability and an eye for goal.Since making his debut in the FA Cup clash against Wolves on January 7, Gakpo has taken 12 shots across all competitions but has failed to register a goal for the Reds. His finishing certainly requires improvement as Liverpool look to end their goalscoring woes.#2. Mykhailo Mudryk looks set to light the Premier League on fireLiverpool FC v Chelsea FC - Premier LeagueMykhailo Mudryk made his Premier League debut for Chelsea as he replaced Lewis Hall in the 55th minute.The 22-year-old signed from Shakthar Donetsk earlier this month after Chelsea swooped in to complete the transfer, amid serious interest from Arsenal. Despite being a fairly unknown commodity on the European scene, Mudryk commanded a fee of about £88 million, making him one of the most expensive players in Premier League history.Squawka@SquawkaMykhailo Mudryk's Premier League debut by numbers:35 mins100% tackle success14 passes attempted13 passes completed7 duels won4 touches in opp. box4 x possession won3 tackles made2 take-ons completed1 foul won1 shotNo player on the pitch completed more dribbles. 🩰52531121Mykhailo Mudryk's Premier League debut by numbers:35 mins100% tackle success14 passes attempted13 passes completed7 duels won4 touches in opp. box4 x possession won3 tackles made2 take-ons completed1 foul won1 shotNo player on the pitch completed more dribbles. 🩰 https://t.co/rhgPs0rsOkThe Ukrainian lined up in his preferred slot on the left wing and made an instant impact. He displayed the pace that he is renowned for and was a constant threat on the wing for the majority of the second half.He found himself in several great positions, even making a couple of intricate dribbles in Liverpool's penalty box. With his career still ahead of him, it is doubtless that he has all the skills necessary to take the Premier League by storm.#1. Thiago Silva continues to be Chelsea's standout perfomerLiverpool FC v Chelsea FC - Premier LeagueThiago Silva started at centre-back for Chelsea in today's fixture against Liverpool at Anfield.The Brazilian has been a mainstay in Chelsea's defense ever since he joined and showed yet again why he continues to be one of the best defenders in world football despite.

He was up to the task every time Liverpool progressed in attack.With Chelsea hoping to grab a top-four place, Silva's leadership and ability will certainly be key in the second half of the season.
