Upfront cost means very little other than for cashflow. You still have to pay the full cost.
He was signed as a striker for a team who were in desperate need of goals and he hasn't scored in 2 seasons. It's clearly not been a successful piece of recruitment.
Absolutely false.
1: There was ZERO money to sign players. ZERO. Beto and Chermiti signed for ZERO upfront.
Upfront cost means players typically cannot be signed which would have left the club with DCL as the only centre forward for the entire season.
2: Your second paragraph is utter nonsense. He certainly was not signed for a team who "blah blah blah" he was signed as a LONG TERM DEVELOPMENT player.
That is not someone signed for the immediate requirements of the team.
Is "long term development" under Sean Dyche for 1 season and then a long term injury a reasonable timeframe to judge him?
No.
Is 15 mins over 2 games and then thrown in vs an imperious Chalobah today going to provide a clear verdict on a player?
No.
If by summer hes doing the same as today then loan or sell.
But lets give him a chance.
