When you look at what went wrong on their goals tactically. Murphy (a right winger) was supposedly playing at right back and was so obviously often out of position all the game that Hayden (a central midfielder) then filled that slot both in attacking phases and defensive phases. This left huge space between him and Lascelles (centre half, not fit, had covid, been crap for over a season) and Leeds were easily able to exploit it .
It's the tactics from Bruce, as well as his terrible habit of playing players out of position. Murphy is a WINGER do not expect him to be a decent right back, and Hayden is a MIDFIELDER !! There are three right backs already in the first team squad ffs. You've also got the coaching staff and Bruce's refusal to do anything about these galling errors which were evident early in the first half . I can see it and most viewing could see it . Is it too much to ask to expect a professional football manager and half a dozen Continental licenced coaches to ?
Also no communication between players especially senior players. Why wasn't Hayden sorting Murphy out and Lascelles sorting out Hayden ? Look when we concede even a chance there's never anyone bollocking their teammates. If you've played at any level that's a basic requirement, "Oi fucking pick him up or oi stop bombing on ". The basics aren't being demanded at this club . Not even the fucking basics .
