Liverpool’s defensive improvements over the last two seasons cannot be understated.
From having a worryingly leaky defence, Liverpool’s back line is now solid and forms the perfect foundation for them to launch a promotion challenge.
Much of that is down to the signing of Virgil Van Dijk. The towering Dutchman is a rock at the back.
But the emergence of youngsters Trent Alexander-Arnold and Joe Gomez has also helped.
Gomez slots in alongside Van Dijk in central defence or at right-back and he looks equally accomplished in either role.
Alexander-Arnold’s rise to the top earned him a World Cup spot and the 20-year-old right-back is going from strength to strength.
And the form of Gomez and Alexander-Arnold means Jurgen Klopp will have no regrets over letting Brooks Lennon leave.
When Liverpool sanctioned Lennon’s permanent exit, he was considered to be a young winger.
But at Real Salt Lake in the MLS, the 21-year-old has reinvented himself as a right-back.
He is highly rated in the United States and could even make his senior USA debut at some point soon.
Attack-minded right-backs are useful for Liverpool, who spend more time going forward than sitting back.
But Alexander-Arnold is much better than Lennon. Despite Lennon’s impressive form for Real Salt Lake, Liverpool will not be regretting their decision to let him leave.
