I'd say for example Tosin is an ideal player to be sent to Breda, if he (or the teams involved, obviously :D) fancies it. He's a CB which they are apparently in need of, and he will hardly get a look in in our first team, given that we are extensively searching for CBs but already have in our hands quite a few of them...
Though Tosin needs now men's football, I think he also showed against Chelsea that he is probably up to the challenge. Given the fact that the lesser sides in English football hardly dick around with youngsters in their defence, especially with players on loan, the 2nd tier of Netherlands could be just the ideal platform for him to develop. In fact, he should already play at least in a level of the Eredivisie, but still...
Other than him, I can only see those players to be included in next year's loan dealings who are either not even that young anymore, or just will hardly ever play for us, or are already playing there, see our two lads.
To be honest, I'd rather see both Garcias, Brahim and co. to have this summer with Pep and the first team, and then play for our EDS/U18 with the occassional run out in the first team, or at least some nearly-regular first team training. Not to mention Byrne, who has already proved himself in the first tier. And the same applies for Davenport I think, i.e. let him develop further more here at City this season, at least Pep might recognize sooner the gem we have in him. :)
I can't decide what to think about Barker and Bryan, though. Both our still young, but sometimes it feels like they have been here forever and didn't progress enough recently. I'd like if both would be involved in the summer with the first team, but eventually they will need (a good) loan elsewhere as there will be hardly any capacity for them.
