It's very hard to predict who is strong among Pakistan and Bangladesh because both teams have same level of performance these days. The main issue with Bangladesh is consistency i.e. once they perform well in one match or a series they do opposite in next matches. Pakistan has finally made a bold move of dropping main players like Babar Azam, Shaheen Shah who were struggling to score runs or taking wickets. Pakistan team is in state of rebuilding and that's a good opportunity for Bangladesh to grab another T20I series victory.
Honestly It was look like a balanced fight from both side but surprisingly Bangladesh takeover thing and show his complete dominance over Pakistan, which was totally unexpected. But I think experiment to utilize youngster cost them that defeat, morever Bangladesh bowling lineup took advantage of home ground experience and took early on wickets and then keep execute pressure on them which results In Pakistan failed to put huge number on board. While on the other hand lack of experience in bowling lineup unable to get them enough wickets before they get the required target and thus Pakistan officially lose the first match of series.
