I think it's very risky in any game (CL or league play) Arsenal could have scored 3 goals easily themselves, of-course any bet has risk, but speaking from experience I've won my fair share of no next goals and lost quite few, I usually play mines late in the match 80-83minute, w/ heavy juice..........like I said I've won many but w/ the juice you basically lose all you made with just a couple losses.
.....pick and choose your spots, and you can make some $, otherwise it's a waste of time, and unfortunantly $!
Oh, 1-0 lead surely dosen't mean a team shuts it down, I've been burned by late goals when teams have 2-0, 3-0, 3-1 leads w/ no need to score again...........when you win those it feels like stealing, when you lose you cannot make sense of it!
