Before Ronaldo's arrival at Al Nassr, Talisca was already an important player for the team's squad, he even scored 20 goals last season. If it's not wrong, in Talisca's first season with Al Nassr, he also scored at least 20 goals with Al Nassr. Since Ronaldo joined this team, there have been changes in the Al Nassr squad.
Even though Ronaldo is the main target for Al Nassr at the moment, that does not reduce Talisca's sharpness and how important he is at the club, he has scored 4 goals and 2 assists, and 4 other goals in different competitions. Talisca has managed to appear consistently, maybe he won't be Al Nassr's top scorer again this season, but without him Al Nassr is very likely to experience problems in attack, so keeping him at the club is no less important than keeping Ronaldo.
