I think Archer needs to go on loan for a full season next year (in the champ), he isnt too old either, the same age as when Tammy was with us, a full season would do him good.
I wouldnt send him to Norwich tho, they play with 1 striker and have Pukki, who is a proven and season championship performer, he needs to go somewhere where he is a starter and gaining experience, not as backup to probably one of the best strikers in the league.
Ofc, i agree he should go to a team that plays the right way, and is aiming higher up the table, but Norwich would be a terrible choice imo.
