Fair enough. I think Kerkez would be a better fit for you than for Liverpool and Robinson a better fit for Liverpool than you but you probably need a Robinson more than they do if that makes sense.It's not that old for a player generally, but for a new signing at any sort of significant fee it's definitely older than ideal for most top sides.
For example in Liverpool's case I can only think of four 27+ year old outfield players they've signed in the last decade or so. Namely Endo (€20M), Thiago (€22m), Klavan (€5m) and Milner (free). It just isn't the profile of player they look to spend money on.
