Couldn't agree more. We desperately need another experienced competent midfielder. Ideally I'd see him being able to cover both the holding mid spot (Riera) and a more advanced mid spot (Lia) but when everyone's available be good enough to start ahead of Lia. Ridenton can provide bench cover when needed (think that's his level currently), and Manny can go back to FB.
Just to let you know, Chris Bale (4 World Club Cup tournaments, ASB player of year 2012, ex-Bristol Rovers pro) has just retired from playing with ACFC.
