Not sure if I agree with the Ricardo narrative on here. Neither he or Justin are a left-back and playing with a right-footer in that position helps no-one. Therefore, you’re left with the option of Justin/Ricardo at right-back.
For me, Justin is more dynamic and a better equipped defender to handle premier league wingers - where does that leave Ricardo? Honestly don’t think cooper is getting it far wrong at all.
Also, some people are extremely quick to write of BDCR. Not hard to work out why he’s been favoured at the start of this season.
