If next season continues in the same way as the past twenty-something games, Ange won't last.
We need a proper number 9 who can help on set pieces at both ends.
To address the same issue, I'd look to replace Porro with a player who is also comfortable as a centre half, same as Woolwich and Man City have at at least 1 fullback position (very often both).
A defensive midfield player who is 6ft plus also helps. We are too small as a team. Look at Rodri and Rice for example, players in that mould.
So much work, and is Ange the guy? How the season is ending, probably not. At half time I'd have been fine with him being sacked but in a calmer place of reflection, he'll get next season to work a miracle. I just don't think he will.
