It's hard not to think that Lionel Messi and Luis Suarez are the greatest goalscoring duo in the 21st century.

At Barcelona, the two South American superstars forged a deadly partnership and defenders across the world simply had no answer to their magnificence.

Messi and Suarez both found the back of the net with terrifying regularity in Catalonia and in 2015/16, they achieved the seemingly unachievable.

Across all competitions that season, the world-class forwards scored a combined total of 100 (yes, ONE HUNDRED) goals.

That's just absurd isn't it? Unsurprisingly, that total has not been equalled or surpassed by another double act since the turn of millennium.

But that doesn't mean we can't celebrate the other great goalscoring duos in the 21st century and using Transfermarkt, we've worked out the most prolific from each season since 1999/2000.
