Neymar can never be a good option for a team like Dortmund and I'm sure they know this player is far from his good form and he can't have good performance anymore. Also as far as I know Dortmund usually prefers to use the younger talents in the team instead of buying expensive and older players like Neymar.
Neymar is a superb soccer player but given Borussia Dortmund transfer policy and financial limitations, it appears doubtful that they will try to sign him as a winger. Dortmund is renowned for developing young players and emphasising team building over acquiring expensive big stars. Neymar expensive salary demands and injury history may further discourage European teams from giving him any consideration. Given his availability and potential fit with the team plan, Serge Gnabry might be a more practical target for Dortmund if they are in the market for a winger. Given the financial considerations, any prospective deal for Neymar this summer might be restricted to Saudi teams.
That's right, if Dortmund try to take Neymar now it feels very pointless for a team contribution but if for business, I think Neymar has it all. We know he is also a star player even though in recent seasons he has experienced a decline in performance due to frequent injuries. On the other hand, Dortmund will be increasingly hampered from producing other talented players and indirectly their business will be quite disrupted if Neymar joins. What is clear right now is that the possibility of Neymar joining Dortmund feels impossible but for Gnabry I quite agree that Dortmund will sign him.
Obviously that's very unlikely, because Dortmund is a club that produces great players and not bring in star players. After all, even if for example Dortmund brought in Neymar but still, it would not guarantee that Dortmund could win the Bundesliga title. So yeah, I think it's just a rumor that obviously wasn't going to happen, so it's not true at all. Except, for example, the rumors about Neymar going to Bayern Munich, maybe that still makes sense too but because Neymar has a big salary. So it seems, the Bundesliga is not the right place for Neymar.
