It's almost unimaginable now that a club of Bayern Munich's stature would be interested in forgotten Chelsea man Callum Hudson-Odoi, but that was the reality in 2019. A two-year pursuit would culminate in a rejected loan offer that included a whopping £70 million ($90m) obligation to buy, with the Blues steadfast in their resolve to hold on to one of the jewels of their academy.
