The Clarets boss admitted he was keen on the 21-year old Tottenham striker and attempted to bring him to Turf Moor prior to his breakthrough season which has yielded him 30 goals for club and country this term.
"But he's a good reflection of when us as managers speak about players going on loan, because loans don't always have to be the glory loan. He's had his ups and downs on loan but that can be a massive part of a young player's development.
"It can be that kind of process and you have to stick at it as a young professional."
Dyche added: "We didn't try to bring him here, other than the fact we tried to bring him here."
