Visiting Sporting\n\n The English-language press often refers to Sporting Clube de Portugal as 'Sporting Lisbon', much to the chagrin of its fans. The 50,000-capacity Estdio Jos Alvalade is only 2kms from Benfica's ground, but the Metro stop you need is Campo Grande (not Alvalade) on the Linea Verde (Green Line).
It's about 1 3/4 miles between the two - how about a rather swift walk! Maybe just leave the Benfica game 5 mins from the end if you see that the score wont change, and you will be one the first to leave the stadium, jump on a taxi to Alvalade stadium which is not that far, just over a mile.
