Like you say, I dont think we're asking for a midfielder(s) that will grab us 10+ a season, but when you look at the stats above, our potential starting 2 midfielders have scored not even 10 between them in 3 or 4 seasons... and 2 of those have been in the 2nd tier of football...
I know this last year we've played Cook and/or Lerma in a more sitting role due t Parker's preference of 2 advanced players supporting Solanke, but Anthony will never have played at this level before and Solanke is still almost 'untested' at PL level... We really do need to be prepared to add some goal scoring quality into our central midfield, which will likely result in either Lerma or Cook being dropped... Which is unthinkable really, but the reality of trying to stay in the PL...
