I wouldn’t be trying to play players out of position just because of a lack of options up top. I’d start either Watters or Marsh alongside Cosgrove & basically tell them to run their ******** off feeding on knockdowns & stretching the Mansfield defence for an hour & then bring the other on. This is assuming Jalo is injured. Although I don’t see Jalo as a starter so I’d still start one of Watters or Marsh but it would potentially change things in terms of substitutions if he is fit. I get the idea of moving Phillips further forward but his knack is arriving late & finding space like a Lampard type, not actually starting as a forward. I won’t comment on Craig or the new keeper as I’ve not seen them play.
I reckon Marsh and Cosgrove could be effective together. Think Marsh playing off a big man could work well.
