Joe Allen described Brennan Johnson's development over the last season as "incredible".
The 21-year-old spent the duration of the 2020/21 campaign on loan at Lincoln City and has enjoyed a meteoric rise since his stint with the Imps. Johnson was a key figure as Nottingham Forest gained promotion into the Premier League last term while he has also impressed at international level, scoring twice in 13 caps.
And Joe Allen admits Forest would have struggled to keep hold of Johnson had they remained in the Championship. "I have been so impressed with him," said the Swansea City man.
