Latest is that you can also cross off the dutch lad as he is not due at ewood till 26th july (4 day trial)
I found this:
"In short, El Hamdaoui will go to Ewood Park on Monday the 26th for a trial period of four days. Excelsior's technical director (Kelder) made it clear to BR that in case of a transfer El Hamdaoui will cost a considerable amount of money (for our standards). He still has a two-year contract and Excelsior agreed with the trail period only after BR's official invitation.
As for El Hamdaoui, he's young and talented, definitely more of the 'arte' than the 'labore' type "
