Manolas would be bonkers and surely cost upwards of 40 mil.
Although with the talk of Keane and Manolas - both right-sided CBs - I'm not sure how we'd line up. I'd have thought we'd be looking to replace Mori on the left rather than Holgate on the right.
Manolas usually plays left side though mate, even though he's right-footed.
In a three though, I agree - always better to have at least one left footer IMO.
