I was certainly too optimistic regarding Daka. I thought we had unearthed another gem in the Kanté/Mahrez mould.
When I look back, I tend to err on the 'too optimistic' side, perhaps misled by many genuinely good appointments from the wilderness.
Keith Gillespie was another that comes to mind. An International, what could possibly go wrong?
Peter Taylor - a clever choice with a good lower league pedigree!
Brendan Rodgers - the best choice in years! How shrewd is that appointment?
Lots of others I suppose.
On the pessimistic side: I certainly wasn't convinced by Robert Huth: too wooden, poor injury record, long gone from Germany's team, couldn't get into the Stoke team either. Who'd have thought he'd turn into Leicester's Berlin Wall and an Immortal?
