One was already relegated and conceded loads of goals , the other needed to win to have any chance of a play off place so we’re very likely to leave themselves open at the back . Not saying it didn’t work for those two games but are you saying we don’t need a decent wingback who plays that role regularly and and has proven himself as capable.
We still need cover there if you Play Johnson in that role and it does work as with international call ups, injures or suspension he will not play every game .
It’s also a demanding role so three games in a week might be to much for anyone , all I’m saying is we need a wingback anyhow as Lowe basis his tactics on that formation and no one else in our squad has exactly shone in that role .
