He's there to give Odobert and Moore time to develop. Don't want to be throwing Moore in and he doesn't perform well impacting his confidence.The argument for his signing was that he was meant to be used as a backup, now people want him to start. Is Son the player he was 2-3 years ago? Absolutely not but he still gets 10-15 goals in a bad year. I’d even advocate for Moore getting the minutes Werner would be normally get if Son’s form nosedives. Don’t see the point of using Werner as a starter if he’s not a long term option.
Ease him in slowly. By the end of the season him and Odobert will hopefully be ready to be starters for next season.
