Exactly, the best hand in a negotiation is having no problem in walking away. If Dortmund don't budge (as they are an arrogant club and think they're bigger than what they actually are (Bayern's woman)), we have no problem in going a season without a striker. I suspect Ferran will be moulded in that role next season if this becomes a reality with more first team football for Delap too.
This also sends a really positive message to Haaland too. "We only want you and we are ready to wait for your release clause next summer if Dortmund aren't willing to budge on your price." I feel this is also why the reports on "City alternate targets" from reliable City sources have completely died.
