The 21-year old left the Reds last summer to join the Blades, having found it difficult to break into Jurgen Klopp’s first-team.
However, Rhian has struggled to nail down a starting role at the Bramall Lane outfit, with just nine top-flight starts to his name and is yet to open his account for the Yorkshire club who are Premier League bottom at the moment and are on course to be relegated.
John has insisted Brewster had to depart Anfield for Sheffield United as no other big top flight sides were going to sign him, while the Blades, who finished ninth in the 2019/20 term, were a great option for him.
Barnes revealed the move has not worked out for Rhian, but stressed it was a was a gamble well worth taking with the talented striker being at a crossroads in his career back in October.
“With Rhian Brewster, he had a chance to go to a Premier League team [Sheffield United]”, he told Bonus Code Bets.
“Of course, they look as though they’ll go down [to the Championship], but at the time they were a top ten Premier League team.
“For Rhian Brewster to go to a top ten team and play regularly was a good move for him.
“Unfortunately, it hasn’t worked out, but at the time, people thought it was a good move, so you never really know [if it is going to work out].
“To give him a chance to go to the Premier League, you can’t turn that down.”
