Big picture
Sri Lanka can breathe easy. Or can they?
Having been blown away by Afghanistan and then having to use every ounce of firepower to get past Bangladesh, they will once again face a trial by spin. Against the Rashids and the Mujeebs. However, the current Afghanistan team is beginning to establish a new bowling order. Their fast bowlers Fazalhaq Farooqi and Naveen ul Haq have been the perfect prelude to the spin superstars. So as a batting unit, there's unlikely to be any respite.
Does the current line-up have the confidence to take on bowling straightaway? In their virtual knockout, Sri Lanka had to go for broke, for a flight was waiting to take them home otherwise. Can they replicate a similar mindset with the stakes significantly higher?
Chris Silverwood's focus is on bringing back Sri Lanka to their refreshing approach to white-ball cricket that revolutionised the ODI game in the 1990s, the kinds that gave opponents nightmares when Sanath Jayasuriya and Romesh Kaluwitharana destroyed attacks with disdain.
However, that is easier said than done. The proof lies in the pudding. Saturday will be another opportunity to test that.
Afghanistan have proved they're giant killers no more. UAE conditions are as good as home conditions. Most players are residents here, and train and play all year round on pitches such as these, and in weather far more oppressive. What they will want to guard against is complacency.
So far, they haven't been tested while batting first. How they approach it - should this scenario play out on Saturday - will be interesting to watch.
Afghanistan have the edge but having just about stopped the door from shutting them out of their own party, they will now want to barge it open.

In the spotlight
On T20I debut, Asitha Fernando won Sri Lanka game that even his teammates thought had slipped away. His 10 out out of three balls helped clinch a thriller to put Sri Lanka in the Super 4s. Against Bangladesh, Asitha seemed a tad nervous and sprayed the ball around even as the Bangladesh top order took him on. He finished with 1 for 51 off his four overs. Now, he'd be looking to impress with the new ball, which is his primary skillset.
Afghanistan are slowly beginning to establish an identity beyond their globetrotting T20 superstars. Among those who putting themselves high on the radar of franchises around the T20 circuit is Rahmanullah Gurbaz. The hard-hitting 20-year-old was given out on zero in the Asia Cup opener but overturned the lbw call on review and went on to take Sri Lanka's attack to the cleaners by making an 18-ball 40 in a low-key chase. Can he rise to the occasion? Now the stakes are high, and a Super 4 game win first up could set them on the road to the final.
Pitch and conditions
The surface in Sharjah will be the same as the Pakistan v Hong Kong game. There is likely to be some rough patches and dry spots that could aid the spinners. That said, the ground dimensions are significantly smaller than Dubai, and both sides have batters than can take surfaces out of the equation. So far, there hasn't been any dew across both venues. Toss should not be a deciding factor.
Team news
Both sides have a fully fit squad of players to choose from. They are unlikely to make changes.
Sri Lanka: 1 Pathum Nissanka, 2 Kusal Mendis (wk), 3 Charith Asalanka, 4 Danushka Gunathilaka, 5 Bhanuka Rajapaksa, 6 Dasun Shanaka (capt), 7 Wanindu Hasaranga, 8 Chamika Karunaratne, 9 Maheesh Theekshana, 10 Asitha Fernando, 11 Dilshan Madushanka.
Afghanistan: 1 Hazratullah Zazai, 2 Rahmanullah Gurbaz (wk), 3 Ibrahim Zadran, 4 Najibullah Zadran, 5 Mohammad Nabi (capt), 6 Karim Janat, 7 Rashid Khan, 8 Azmatullah Omarzai, 9 Naveen-ul-Haq, 10 Mujeeb-ur-Rahman, 11 Fazalhaq Farooqi.
Stats and trivia
Hazratullah Zazai and Gurbaz are the second-most prolific pair for Afghanistan in T20Is. They have eight fifty-run stands in just 21 innings together, including a 37-ball 83 against Sri Lanka last week.
In 13 T20Is this year, Sri Lanka have conceded runs at 8.21 during the powerplay at an average of 42.73. While this average is the worst among all Full Members, their economy is third worst, behind England and West Indies.
Mujeeb ur Rahman has a prolific record in Sharjah: 10 wickets in four T20Is.
