After last summer (and how this season has duly panned out), I think Rodgers and Liverpool have to be very careful when it comes to looking at players from PL clubs below them. It's clear that Lambert, Lallana and Lovren have not worked this season - and to be honest, if you go back further, you would put questions marks over the likes of Allen (Swansea), Mignolet (Sunderland), and Enrique (Newcastle). Hell, Adam (Blackpool), Carroll (Newcastle) and Downing (Villa) have all already left again. I think the Liverpool fans will be highly sceptical about potentially signing more players who PL clubs below them, who on first glance wont help them compete with even Arsenal or City, let alone Chelsea. And that in turn might scare Rodgers and the Liverpool board off - they must know that they're on dodgy ground with the Liverpool fans as it is, given the last 10 months. They must also know that they've wasted enough money as it is.
Is Tripper good enough for Liverpool? I'm not sure, potentially. Can I see Liverpool bidding for him? Absolutely not.
Given that Everton have Coleman and Utd may well have Clyne, I'd suggest that if we want Tripper, only Spurs could potentially get in our way.
