The 21-year-old left-back's poor turnover gifted the hosts a late winner in Saturday's 2-1 defeat.
Sherwood was speaking to the club's official website after seeing his side fall to their second straight defeat at Selhurst Park, when Bakary Sako capitalised on Amavi’s awful giveaway to net an 87th-minute winner.
The hosts had earlier taken the lead through Scott Dann’s powerful header 20 minutes from the end but it looked like Villa had rescued a draw when debutant Adama Traore equaliser just eight minutes after his 69th-minute introduction, dribbling past two Palace defenders before forcing Pape Souare to turn the ball into his own net.
Sherwood’s men would see the point slip through their hands in the closing stages, however, as Amavi – situated in his own half – tried and failed to dribble past scorer Dann, who robbed him of possession and picked out Sako to deliver the late blow.
After standing out as Villa’s star performer in their first two games of the season, the mistake was a cruel reminder that the summer signing is still far from the finished article but his new boss believes he will learn from it and come back stronger.
Speaking about the French left-back’s error at the final whistle, Sherwood said: “That's what you will get with young players, unfortunately. Jordan hasn't made many mistakes since he's been here but that's one and he will have to learn from it.
“We have a lot of good young players. We have added a lot of youth to the squad. Unfortunately you will get ups and downs with young players.
“I have been in that boat before, I have seen it. But I know how to develop them.
“He made the wrong choice. But you have to learn. He will - he's a good player.”
Amavi, 21, joined Villa from Nice last month for around £10 million, having racked up 36 appearances and four goals last season to help the Ligue 1 club to an 11th-place finish.
Labelled one of the French top-flight’s most exciting prospects, his impressive form attracted reported interest from the likes of Arsenal and Atletico Madrid earlier this summer [h/t Daily Mail], before Sherwood convinced him that Villa was the best place for his development instead.
After starring in pre-season, the France Under-21 international went on to steal the show in both the 1-0 win at Bournemouth and subsequent 1-0 home defeat to Manchester United, as the claret and blue faithful hailed him as the answer to the club’s long-running left-back problem.
There is absolutely no reason to think he cannot be either but, after Saturday’s blunder, fans might want to brace themselves for a few more teething problems from both him and the other summer arrivals over the coming weeks and months.
