I think we haven't utilised his strengths over time because we have stopped being a counter attacking team and his threat (can't believe I'm using that word now !) was running in behind rather than scoring goals v a team that has already set its defence and midfield with little space inbetween
That doesn't excuse the abject finishing we're now seeing which is the result of a total loss of confidence. Still prefer him to Ayew though although that's a bit like saying I'd prefer to shit my pants on a night out rather than mess them with a gush of diarrhoea
