According to Sky Sports a deal for Quincy Promes is unlikely to happen for reasons beyond Saints control.
It seems that the issue with Saints signing Quincy Promes is not so much one of Spartak Moscow's asking price not being met by Saints nor the player being unwilling to join, but according to Sky Sports the fact that the Russian club are unable to find a replacement for him.
Sky say Saints have matched the asking price, but now Spartak are baulking at the deal claiming they want a replacement in place before they let him go.
They have had plenty of time to do so given Saints lont term connection to him, but they just don't seem to want to let him go as was evidenced from recent leaks to the Russian football media suggesting the Promes did not want to leave, later rubbished by the player himself on his social media.
So it seems that Spartak are trying their best to scupper the move, however it could be just a tactic to get a bigger fee, it will now depend on whether the player himself puts pressure on the club and Saints up their offer to persuade Spartak that it is an offer they can't refuse.
