As not every player who moves from one club to another within the same league is a rip-roaring success, it’s very difficult to know how someone will perform if moving up a level or from another country.
This is not something which has unduly concerned Liverpool in recent years. They have had great success with players such as Andy Robertson and Gini Wijnaldum who they purchased from recently relegated Premier League clubs, and others have joined from overseas and slotted into the side almost seamlessly.
Their business this summer looks set to put this issue to the test once more. However, statistical analysis – which remains the bedrock of how the Reds analyse and scout players – suggests that Kopites need not fear about how the likely Liverpool new boys will perform in the English top flight next season.
