striker and a midfielder 

There's a bit of talk about Ibini - a free agent and played under Robinson at Vancouver. Would welcome that signing. 

The other rumored player is Welsh midfielder Joe Ledley, formerly of Cardiff, Celtic and Palace. 77 caps for the national team and currently sporting a Jedinak-like beard to boot.  

they will have to get rid of another marquee 

We have no marquees currently. But we have maxed out our visa spots. We need to either terminate Ridenton's contract, or end Burns/Arroyo's loans early, if we are to bring in Ledley. 

i guess the obvious one is ridenton then 

On the contrary, terminating Ridenton's contract sounds the most expensive option. 

Surely O'Donovan is close to citizenship? Or is it possible Hoolahan is just broken for good and we're replacing him?

Both Ledley and Ibini would be good signings but looks like neither have played any real games for a long time so would expect they will take time to get upto match fitness. Might be a bit late to save the Jets this season,so hope they are on longer contracts.

Ibini could be the Nabbout/Champness hybrid we need, especially with Arroyo only on loan (I'd be tempted to keep him if we could). Knowing Bernie's ways, we'd probably play him into fitness/form and he'd be off. 

Ledley could be a real game-changer, but like you say we don't what state he's in. Says he wants to play Euros but he's been bouncing around a while now. The more I see of Thurgate in the middle, the more I like too.

Interesting to see what Robinson's connections can bring us. 

So why was Ledley not in the match day squad last weekend, he was named in the extended squad.. Are they still sorting out a visa issues?
There was a pic that showed Ledley and Riddenton training together at the jets ?

I believe he is not fit enough yet.
