Bring Tarkowski in.
Watched him for years at Brentford (lived in London so ended up seeing more them than Everton, sadly), but always thought he 'd be comfy at Prem level and he is.
+'s
Strong
Reads game well
Can pass
Great team player.
On a free, won't want mega-wages.
Not 'glamourous' enough for the 'top' clubs.
Would help Keane.
DOesn't miss many games
-'s
Lacks pace, albeit has clearly worked on this since Brentford days
Could score more (even Keane chips in much better on this point).
Get it done... having a stable defence will drasticall improve our patchy midfield becuase we'll have ball players playing to strengths rather than doing a less than 50/50 job of filling in at the back becuase they feel they need to.
