I think it’s a big possibility
Yes :) they train in Germany and in the Neatherlands. They have good horses and good trainers. They have the money to pay for a good equipment and good caring around the horses. They are motivated and wants to get on the top. Also why not :) if they keep up training in good conditions they can be on the top.
They are staying at Holland most of the times and working with Tops so they are not different than European riders. Sheikh Ali's horses are Qatar's horses as he is the family of the Emir and also Bassem is a very good person and he is talented so Qatar government supports them. And there is no reason not to be a top rider. He already moved 90. At FEI list.But as I am a rider in Middle East I know very well most of the time we have a missing basic, when we were kids we didnt have a good system like Europe or States. So these countries are developing with the system for future riders.
In my opinion, they are getting more known in between the other horse riders. Also their league team, the doha fursun, is going higer and higer in the league ranking, so I think they have more importance in the league and also they are winnig a lot of longines global champions tour competitions. Step by step they are getting stronger in the competition and in between the other horse riders, so one day they would become one of the best horse riders.
Yes they could of course! They have good horses, lot of money, they are motivated, they have everything to be at the top level soon! :)
