Lampard wasn't in place 12 months ago. He was hired on Jan 31st, officially, the day that we signed Dele and VdB. Neither worked out though VdB more due to injury.
The DoF came in place in Feb and as of yet has so far failed to hire a head of recruitment (or officially announce one). The head of recruitment at any club is the one that should work directly with the manager to establish what players are required. Whether a DoF is in place or not, every club should have a head of recruitment.
Everton signed 8 players in the summer: Tarkowski, Vinagre, McNeil, Onana, Coady, Garner, Gueye, Maupay.
For a lot of reasons, Everton were limited in what they could do. The combined up front fees paid for those eight players come to about £25m. Richarlison was sold, stripping the side of one of the last bits of quality.
The summer recruitment was okay to a point. But lacked quality where it mattered - and where the most money needed to be spent, which was in the atatck.
