60’s. Carlo Sartori.
70’s John Fitzpatrick.
80’s. Everald La Ronde played left back for AFC Bournemouth in their 2-0 FA Cup win over Manchester United in January 1984.
90’s. A catch question this, Simon Davies was a Wales qualified winger who played twenty times for Manchester United in the mid 90’s – his only goal for them came in the Champions League against Galatasaray.
00’s. Teddy Sheringham was in the Colchester side beaten 4-1 by City in December 2007.
10’s. Declan Dalley who was one of seven City players in the Wales Under 16’s team of 10/11 who was offered a contract by Manchester United as City, apparently, ummed and ahhed about offering him a new deal.
Bonus question. Wyn Davies is the only Manchester United Welsh speaker I could think of – wouldn’t be surprised if Billy Meredith was, but I couldn’t find anything to prove this.
