Kevin de Bruyne and Romelu Lukaku had the shared experience of needing to escape Chelsea to realise the potential they displayed during their formative years at Stamford Bridge.
De Bruyne ended up at Manchester City via Wolfsburg, while Lukaku's more nomadic route took him to West Bromwich Albion, Everton, Manchester United then Inter Milan before he arrived back at Chelsea last summer.
Lukaku, who cost a club record £97.5m, always seemed destined to return to Chelsea at some stage, whereas De Bruyne - along with Liverpool's Mohamed Salah, also on the books at Stamford Bridge - must always be regarded as one that got away.
