Question: When was the football star who backed out due to relay controversy signed by Barcelona?

Knowledge 1: 2008 Summer Olympics torch relay
The outreach director of HRTR, Susan Prager, is also the communication director of "Friends of Falun Gong", a quasi-government non-profit funded by fmr. Congressman Tom Lanto's wife and Ambassador Mark Palmer of NED. A major setback to the event was caused by footballer Diego Maradona, scheduled to open the relay through Buenos Aires, pulling out in an attempt to avoid the Olympic controversy. Trying to avoid the scenes that marred the relay in the UK, France and the US, the city government designed a complex security operative to protect the torch relay, involving 1200 police officers and 3000 other people, including public employees and volunteers. Overall, the protests were peaceful in nature, although there were a few incidents such as the throwing of several water balloons in an attempt to extinguish the Olympic flame, and minor scuffles between Olympic protesters and supporters from Chinese immigrant communities.

In June 1982, Diego Maradona was signed for a world record fee of £5 million from Boca Juniors. In the following season, under coach Luis, Barcelona won the Copa del Rey, beating Real Madrid. However, Maradona's time with Barcelona was short-lived and he soon left for Napoli. At the start of the 1984–85 season, Terry Venables was hired as manager and he won La Liga with noteworthy displays by German midfielder Bernd Schuster. The next season, he took the team to their second European Cup final, only to lose on penalties to Steaua Bucureşti during a dramatic evening in Seville.
