Celtic are to replay arguably the most controversial encounter in their history, after entering talks to face Argentina's Racing Club home and away.

The South Americans have written to Celtic and received a favourable reply to a proposal to play two friendlies in Glasgow and Buenos Aires to mark the 50th anniversary of the notorious 1967 Intercontinental Cup Final.

Both matches would be played in summer 2017 with Racing determined to mark their most celebrated honour with a rematch.

A Racing statement said: "After writing to Celtic, we received a response from the Celtic chairman Ian Bankier who is agreeable with our proposal. The games will be played in July, 2017 in Glasgow and Buenos Aires to mark the 50th anniversary."

The legendary three-match encounter between Celtic - European Cup winners in 1967 - and Copa Libertadores holders Racing was one of the most bruising series of games in football history.

Celtic won the first leg at Hampden Park but lost the return leg 2-1 in front of 100,000 in Racing's El Cilindro ground, before also losing the decider in Montevideo 1-0.
