I concur, Umar.
Shabbir, Anamul, Nur, Shaker and Nasir are streets ahead of Naeem, Riyad and many others in sheer talent, skills, temperament and winning attitude. These boys are used to winning...and have won many a match for their sides (U19/Academy) from very tight situations. They are totally a different breed.
In my not so humble opinion, Shabbir and Nasir definitely should make the squad for Zim series; if not the WC squad. Shabbir could be our wild card for the WC and the PowerPlay batter we so DESPERATELY need. Some players are ready for international cricket at 19 and many not even in their late 20s. Shabbir and Nasir belong to the former kind. They are ready to be fast tracked into the national folds and warrant a place in the side before the likes of Naeem and Riyad.
