Luis Diaz made a highly anticipated return to playing action on Monday night, coming on for Liverpool in the final ten minutes of their 1-6 win against Leeds on Monday night.
Diaz had been out since before the World Cup started, having suffered a knee injury back in October which saw him undergo surgery. This has led to Liverpool being without one of their best attacking threats for a number of months in what has turned out to be a difficult season for the Reds.
With his return coming in a 1-6 win against Leeds, there will be optimism on Merseyside that the 26-year-old Colombian can provide some of the spark which he showed in the early months of the season to help salvage European football for Klopp. However, what might often go unnoticed is the emotional toll that such injuries take on players' families.
