Ivan Toney is known with his cold penalty in Euro 2024 and honestly I am very impressed with his shot and his penalty shooting style. He can provide some other things for Al-Ahli attacking system too and Firmino with his time in Liverpool shows that he can support his team mates in attacking system very well. Firmino is a striker with his favorite style of ready sacrificing his own benefit and positions in order to help a team scoring goals and wining matches. Firmino is not obsessed with goals scored by himself.
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.
