Yeah the toss has a huge impact on the outcome of the match. India lost the toss in the last match but created a chance to win the match with a flying start from the opening batsmen. But their middle-order batsmen could not use that opportunity properly. Sri Lanka have played fantastic cricket in the last two matches. So if Sri lanka win the toss then they have more chances to win because they have that ability.
Winning the toss definitely affects the match. In almost every match we see the teams batting later getting a bit more advantage. So the toss will play a very important role for today's match as well. The
Sri Lanka team is not weak. However, none of the players in their squad have performed consistently. In the first match against Afghanistan, we are seeing very weak batting from the Sri Lankan batsmen. In the next match, Sri Lanka played brilliantly against Afghanistan. So it is difficult to predict this team.
Although on paper India is the favorite to win this match. Even then, Sri Lanka will not let India win this match very easily. Sri Lanka will continue to fight their hardest to win.
