Roberto Di Matteo, Chelsea, 2012
The former Chelsea midfielder was assistant to new Blues manager Andre Villas-Boas, but when the Portuguese was sacked after just nine months, the Italian was appointed interim boss – and what a few months it turned out to be.
He led the Stamford Bridge outfit to an unexpected victory in the Champions League, beating Bayern Munich in their own backyard on penalties – the first time the club had lifted the trophy in their history.
The success prompted Roman Abramovic to offer a two-year deal to Di Matteo to sign on a permanent basis, but just three months into his contract he was sacked and replaced by Rafael Benitez.
