Albentosa had a decent game against Birmingham last weekend but struggled under heavy pressure towards the end of the game, as the Rams eventually conceded an equaliser.
Simpson has defended him against blame following that disappointing draw, but has challenged him to continue improving.
“He will improve over time once he gets used to English football – not under-21 football or training. He needs to get used to Championship football,” said Simpson.
“When he does, I am quite sure if he improves as he has done since he came in he will be a really good acquisition for us.”
The key test for any player and team is how they react after a difficult result as Derby experienced last weekend.
The positive thing is that the side are in the mix for promotion and still have every chance of securing automatic promotion place by the end of the season.
Albentosa is a good defensive option and his confidence will benefit if he can play well over the rest of the campaign and excel in a promotion push.
Simpson is right to point out that the Spaniard is still very fresh in terms of the English game and may have been initially surprised by the standard of the football in the Championship.
He has all of the attributes to become a key first choice player across Derby’s defensive line and just needs the backing and support to prove it.
