Liverpool's 2020-21 Premier League season can only be described as a mixed bag. The Reds lost their defensive talisman Virgil van Dijk early in the season, which seemingly kicked off a chain reaction of injuries.The side saw at least three starting players miss large portions of the season through injury. This severely hampered their ability to compete for titles in England and in Europe.Mid-season was their lowest point of the year as Liverpool's formidable home record at Anfield came crumbling down. They went from not losing a game in over two years to losing six games on the trot.Nonetheless, the Reds went on to secure an impressive third-placed finish, a feat that many deemed impossible over the course of the season.With Liverpool looking to pull up their socks for the next edition of the Premier League, there are a few key areas that need strengthening. They will need to identify talented signings to enable themselves to challenge their rivals.Liverpool's potential targets this summer transfer window#5.
