Arthur claims he was poised to "establish" himself at Liverpool before a major injury setback halted his ambitions.
The Brazilian was a deadline-day signing at Anfield as Jurgen Klopp added him from Juventus on loan. Arthur has been forced to wait for his opportunity despite Liverpool's mounting injury list, having been handed less than 15 minutes in the Champions League and playing with the club's reserve ranks.
Arthur has been getting himself primed to make a difference in what is a struggling Liverpool side, but an issue with his thigh has set him back several months. The 26-year-old, who had ambitions of making Brazil's World Cup squad, maintains he was ready to positively influence matters on Merseyside, but has been left nursing an injury.
