Feyenoord may not take Miyaichi again
The 18-year-old Japanese winger was bought by the Gunners in January and immediately loaned out to the Eredivisie side, where he quickly became a fans' favourite.
But despite making a huge impression, Van Geel insists a deal to see Miyaichi return is not as clear-cut as people may think.
"Ryo has definitely been of great value to us," he told Voetbal International. "The lad has done very well with us, but we also have to look at our own players.
"In Sekou Cisse and Jerson Cabral we have two players able to work just as well as Ryo in the same position. We cannot turn a blind eye to that.
"Therefore we will go through everything and then make a considered decision whether it is wise to bring in Ryo."
