Sandro was brought to West Brom from Queens Park Rangers in the January transfer window, as Pulis looked to strengthen his midfield options.
The 26-year-old has played three matches for the Baggies so far, and he is hoping that Pulis continues to allow him to impress.
“I felt the love straight away in my first game but I want to show more,” he said. “I want to play and show what I can do.
“I’m feeling good with my fitness and ready to play 90 minutes now.”
Sandro’s initial loan at The Hawthorns is expected to expire in the summer, but West Brom do have the option to make the move a permanent one, according to the Birmingham Mail.
With QPR unlikely to make it back into the Premier League as early as next season, that switch could be an attractive one to Sandro.
His first task at West Brom will be to ensure that he helps the Midlands side avoid relegation.
The Baggies are currently safely clear of the drop zone, but they need a few more victories before the can feel entirely sure that they will retain their top flight status for another season.
