With the signings of Gallagher and Krovinovic and the emergence of Sam Field as Bilic's preferred holding midfielder sub, it's crucial that Harper goes out on loan this window.
The club have got way better in 2020 at getting players out on loan rather than stagnating in our reserves and it is having some success, but there are still a couple of players screaming out for a loan move this window are Harper is the most important one.
A full season at championship or league 1 level, if at the right club, could be the making of him and be the succession planning for next season.
There is absolutely no benefit to keeping him at the club this window, not when we have Livermore, Sawyers, Field, Gallagher, Krov and Pereira to play those positions. Harper MUST go out on loan this window. Him, Soule and maybe even Shotton/Solanke.
