Seems to be a pretty low risk deal for us regardless of outcome:
Stay up, Archer scores goal - he stays and value rockets
Stay up, Archer doesn’t do well - probably the outcome with the biggest downside, but pretty unlikely we stay up without his goals. Have another year of prem money and still a talented asset on our hands
Go down, Archer scores goals - shame we lose him but regain all the money plus 2 million extra to reinvest in the squad
Go down, Archer doesn’t do well - get back 20 million to reinvest and avoid a Brewster situation and further financial worries
