Ajax goalkeeper Andre Onana is set to be at the centre of a summer transfer scramble with Chelsea, Barcelona and Tottenham all in the frame for his signature.
The 23-year-old Cameroon international is widely expected to depart Amsterdam at the end of the season and has shown a preference for a Premier League transfer.
Onana is a close friend of Hakim Ziyech, who will join the Blues at the end of the season having agreed a deal to move to Stamford Bridge during the January transfer window.
