Replacing McGinn, McGeouch and Allan was almost impossible, and so there was always going to be difficult transition. None of the players brought in are bad players, but equally none of them are as good as the players they are trying to replace. And as Lennon has tried to find the best combination, he has fallen into tinker-man role (HOW MANY CHANGES)
Perhaps Hibs would be best served by simplifying things a bit. Play a back four, with Whittaker or Mavrias deputising for Gray while he is injured.
In front of this back four, at home, why not just go for a straight forward 4-4-2 formation, with Boyle and Horgan attacking from wide, and Maclaren and Kamberi as a front two? Centre midfield would be between Milligan, Bartley, Slivka, Mallan and Hyndman.
Away from home or for tougher games, play Kamberi up-top on his own, with an extra man drafted into midfield to make a tight three.
