BBC pundit Helen Ward thinks Brennan Johnson lacks the physical strength that is needed to hold the defenders off as a striker.
Tottenham were linked with a striker in the summer to replace Harry Kane who left the club to join Bayern Munich for a fee close to £100m.
However, they ended up not buying an out and out striker, instead, signed Brennan Johnson on deadline day.
Johnson is a versatile attacker who can play anywhere in the front three. He is more of a Son type attacker than Kane.
Spurs are still reportedly eyeing a direct replacement for Harry Kane and are linked with several names including Brentford’s Ivan Toney, Feyenoord’s Santiago Gimenez and Lille’s Jonathan David.
Johnson started up front for his country against Turkey on Tuesday and during the game, Ward told the BBC Sport website:
“Brennan Johnson, he’s not small, but he’s not quite got that upper body strength and ability to hold a player off as you need to do as a number nine at times.”
With Richarlison out injured, Brennan Johnson is expected to start on the left flank with Son upfront which has worked so well for Ange.
Spurs need a direct replacement for Kane more than ever in January, specially with Son set to be away for a month during the Asian Cup games in January.
