Johnson believes a move to Anfield would suit the 19-year-old ‘down to the ground’.
Recent reports have linked Saka with a stunning move to Anfield.
Saka has established himself as one of the top stars at Arsenal over the past three seasons.
“I do think it’ll be an expensive transfer to pull off because Arsenal wouldn’t want to sell one of their best players to a rival,’ he told BettingOdds.com via Metro.
“As he’s a fantastic player, a young player and English then it would have to be a big deal.
“In terms of Liverpool and the player being interested in a move then I believe that for sure but I just think it would be quite a complex deal to pull off.”
