Wilder has already alluded to the reasons why he has gone back.
Utd have indicated that they have no intention of signing either Panos or Zitty for the option prices. This is down to the financial downturn to our club caused from Covid19.
CW also mentioned that the transfer budget has been cut back since the one previously signed off in January, and that was due to the PL TV payback of about £15m plus the club having to find circa £50m in the summer to buy back the ground and property.
Retsos signing for Utd is just a victim of circumstances. On the plus side, CW can work with smaller budgets and he can probably get more bang for his buck with this money he does still have at his disposal.
Can't miss Retsos as he hardly played for us.
As for Zitty, well as his Chinese club ha e continued to allow him to stay with us until the end of this season despite knowing that we aren't going to take up the option transfer price, means that either they want us to get him fit and involved, or they may still be open to him signing for us, at a lower price. Maybe he is still playing for a move to us permanently.
