Playing as man utd started grt, won 5 PL in a row and won the CL in 1st 2 seasons in a row and since been defeated in 1 final and 1 semi final, but the cherry on the cake is winning the EURO with england in the 2016, which i think is grt cause teh england team is by no means grt (did win 2 games on penalties, and luckily spain got beaten)
anyone won the CL 3 in a row or won the world cup
