The back four operates as a unit and the unit is not necessarily all made up of your best players, don’t mess with it unless you need to.   If it ain’t broke, don’t fix it.   Botman/Burn played against Spurs/Arsenal away and conceded one goal, I’d stick with them, Schar got himself suspended and the replacement was as effective as the original IMO and the more they play together the better they’ll become (as a unit). From the bench Schar also gives you cover for both CB positions, if RCB gets hurt/needs a breather Schar is like for like replacement, if LCB needs a break, other moves over and Schar slots in and you lose nothing.   On the RW, no new signing (should we make one) will play until he’s been Eddie’d and has earned it, again, it’s currently not broken.   Edit: Just a further thought, if Botman can play RCB effectively longer term, it reduces/changes the priority of a RCB purchase, you could go young (cheaper) developmental player rather than an immediate upgrade level RCB, releasing budget for a bigger hitter elsewhere (RW for example).

They've painted their set piece coach on the side of the stadium.      

He's been very good but I still think put your best players in. Shouldn't have to wait for him to drop off before putting Botman in, we should be building on what we've achieved. Murphy has been scoring and assisting but if we signed an RW tomorrow I'd be expecting him to go into the team.
