Let's be honest, any transfer is a gamble, especially one from the continent.
Honeyman doesn't appear to have any competition whatsoever in our squad; he's easily our best midfielder in the role that he plays, so he needs quality competition to push him and ensure his performances don't drop. Plus his injury record isn't the best and when he didn't play last season we really suffered. Seri would come in to push Slater, while Ozan comes in to play in the number 8 role.
None of the new signings would be guaranteed starters as of now (with the possible exception of Allahyar as we don't actually have another quality striker), they're here to create depth of quality to the squad. We saw it with Baxter, he isn't necessarily a better keeper than Ingram right now, but the two pushed each other to be better for us and we saw some great performances from both as a result. A quality centre half would no doubt push the likes of Greaves and Macca to do well too.
