It is not the only factor that makes Ivan Toney is impressive. As far as I know he often made many goals in EPL. Even if he didn't become the top scorer but his name was in the list of most productive strikers in EPL. Yes, he has a great ability in shooting, he will easily score many goals in SPL if Al Ahli midfielders can support him with good assists. Al Ahli also has good wingers that can support him as well.
Ivan Toney seems fit to play together with Firmino. Firmino can be an attacking midfielder, he is very experienced and has good ability in delivering assists. In theory, Toney-Firmino will be good duo for Al Ahli attackers. I'm very sure Firmino won't be too obssesed to score goals as many as possible. He must be ready to play as an attacking midfielder.
Yeah, with the arrival of Ivan Toney, Al-Ahli's performance should improve because previously they had some great players. This will make the competition in the Saudi Pro League even fiercer but somehow I'm not sure if Al-Ahli is aiming for the title I mean they can only compete in top 3-4 no more and Al-Nassr and Al-Hilal will remain the main candidates to win the title. In this transfer window only a few European players came not like last season,
I would say Al Ahli saudi's squad is quite strong this season too. But whether they can compete for the title is not certain. If the performances are not regular, the team will not compete for the title. If they won the first match this season, the team lost points against Al Fateh in the second match. However, Ahli's squad has several talented strikers like Ivan Toney, Riyad Mahraz and Firmino. Also, the midfield of this team is quite strong. If Ahli's coach was more experienced then maybe we would have seen a better performance from this team.
Al Hilal has been in excellent form this season as well as previous seasons. The team won two matches. The overall gameplay of this team is strong. On the other hand, one of the title rivals Al Nassr dropped points against AL Raed in their first match.
