The 19-yea-old winger came off the bench for the last 21 minutes of Saturday's 3-2 loss.
The £7 million summer signing from Barcelona had been struggling to recover from an ankle knock suffered in the second half of last month’s 5-3 Capital One Cup third round win over Notts County, in which he scored his first goal for the club, but he was finally deemed fit enough to be named on the bench for the trip to Anfield.
Subsequently replacing Jack Grealish in the 69th-minute with Villa 3-1 down, the 19-year-old winger proceeded to attempt a match-leading eight dribbles in just 21 minutes – twice as many as any other player on the afternoon – but, having also recorded only four passes, Sherwood seemed far from satisfied with his run-out.
Speaking to AVTV after the game, the Villa boss said: “With Adama, you see the best and the worst of him and, unfortunately, we haven’t seen the best of him today.
“It’s hard for anyone to come on in the Premier League but it’s also very hard for anyone to be expected to adapt so quickly.
“He is a real threat but he can also be detrimental to your side at certain stages and he needs to learn – we knew that from the start.
“We elected to bring in these development players and I’m the one who’s got to work with them. I’m delighted to have that opportunity but it is going to be a roller-coaster ride.”

Villa were 2-0 down on the hour at Anfield after Daniel Sturridge increased Liverpool’s lead following James Milner’s second-minute opener, but Rudy Gestede pulled one back from close range in the 66th-minute to give them hope of a comeback.
Sturridge almost immediately restored the hosts’ two-goal advantage with his second of the game, however, as Gestede’s 71st-minute header from a Jordan Amavi cross proved nothing more than a consolation strike.
Sherwood’s side now sit in 18th-place in the Premier League table after seven games, having gone without a top-flight win since the 1-0 opening day victory at Bournemouth, but the ex-Tottenham Hotspur coach is confident that his revamped squad will turn things around in due time.
“We didn’t want it to be as tough as this and we don’t think we deserve to be in the bottom three with some of the performances we’ve put in,” he added. “In some of the games, we’ve been robbed of points or given away silly goals, more to the point, and I suppose you get what you deserve over the period.
“But we need to eradicate the mistake, make sure we make better decisions in the right areas and then we’ll be climbing up the league.”
Villa’s next opportunity to end their winless run in the league will come on Saturday when they host Stoke City, who are sitting just one place above them in the table on six points.
