"Davies began his career.." football career (you mentioned previously that trained as a marine engineer)
"against England" suitable link?
"in 1919.[1] He made" merge, that first sentence is very brief.
"for their tie against" ***tie klaxon*** (just reading comments on my FAC from a Canadian ice hockey fan has reminded me that "tie" means all manner of different things...)
"Mostyn House School, Parkgate" comma after Parkgate.
"International goals" table is not sortable (?) so no need to relink things. If (however) you make it sortable, please relink the Home Championships each time.
