Blades boss Nigel Clough says Che Adams has a very bright future ahead of him at Bramall Lane, but believes the youngster still has plenty to learn.
The 18-year-old, signed from Ilkeston in November, shot to prominence when scoring a brace against Tottenham Hotspur in the Capital One Cup semi-final second-leg, but Clough, who was impressed with Adams's cameo appearance at the weekend, insists the Leicester-born attacker will be an even better player next season.
Speaking about his possible involvement at the weekend and beyond, the Gaffer remarked: "Che is someone who we have wanted to use recently and had we had already been assured of our play-off place he would have started at Orient, along with one or two other younger players.
"He looked good when he came on against Bradford, but he has struggled in a few U21 matches, he has only showed glimpses of what he is capable of, but he is still growing and filling out and with that his form will have highs and lows.
"But he is looking sharp and powerful at the moment and he is someone we will definitely have in and around the squad because we have very high hopes for the future with him.
"Che is a perfect build; we work on speed and agility with him, more than strength, because he is a good size and lacks nothing physically."
