The match on 16th (Thursday) is extremely crucial for Nepal. It is probably the most important match that Sandeep Lamichhane and his team-mates will every play in their career. They need a win against the United Arab Emirates to overtake Namibia and finish at the 3rd place within ICC Men's Cricket World Cup League 2 2019-2023. If they are able to do that, then they will qualify directly to the 2023 Cricket World Cup Qualifier, and more importantly keep their ODI status. They will keep the current funding levels from ICC as well.
In case they lose the match, they will be forced to play the 2023 ICC Cricket World Cup Qualifier Play-off. Along with that, their funding from ICC will be reduced and they will forfeit their ODI status (the ODI status is just nominal, as none of the full members play against Nepal). Nepal is showing a lot of promise, but all of that will be wasted in case they lose the match on Thursday.
