A troublesome French star... sound familiar?
If Adrien Rabiot, 27, signs for Manchester United, he will join a select group of players who have represented both the city's major clubs.
The midfielder had a six-month spell in City's academy as a 13-year-old, before returning to France.
'Everything was going well but the club did not respect certain agreements, so my mother put a stop to it and we returned to France,' explained Rabiot in a 2012 interview with Le Parisien.
It was not the last time that he would fall out with his club as his chequered career shows.
If Erik ten Hag were looking for a quiet life, he would surely run a mile from Rabiot, whose mother Veronique has guided his career throughout and has clashed with some of football's top operators.
Rabiot was so aghast to be left out of France's 23-man squad for the 2018 World Cup that he refused to be on coach Didier Deschamps' standby list.
