1. Yep.
2. Hyypia is a consummate professional - he'd not say anything different.
3. Loan out now with a deal agreed for a sale in January is one very obvious option, particularly as I believe Hyypia has been 'encouraged' to do similar to get a striker in.
4. Yep.
Like you, I don't have any real knowledge on the PFA's page, but it sounds badly maintained. However, I would think it likely that it lists players who are (or were) available to some degree or another and that would include those available for loan.
I'm not aware of any of our players...
I've heard some interesting bits about Hyypia's heightened involvement in player recruitment recently - really stamping his thoughts and views on targets. I'm pretty sure I posted a week or so ago that I'd also heard that Toko and COG were unlikely to have any future at the club too.
