Realistic transfertargets in rl from my perspective (some may be a bit of a stretch) from the Eredivisie but a far from complete list. Many players attractive to NEC in terms of price-quality ratio are playing second tier like the already recruited Sami Ouaissa from Roda JC
If the player already plays Eredivise than he's a free agent in the summer or has only 1 year left on his contract on the end of the 23/24 season.
The goalkeeper position is so well filled for the next few years that it makes no sense to look at it atm
