Not every great signing hits the ground running.
Andy Robertson arrived at Liverpool from Hull City and spent the first few months of the 2017-18 season sitting on the bench while Alberto Moreno ran up and down the left flank. A year later, midfielder Fabinho was signed early in the summer but didn't play a single minute in the Premier League until Oct. 20. Come May 2019, they were both starting in Liverpool's Champions League final win over Tottenham. And, the following season, both were stalwarts for the eventual Premier League champions.
