The midfielder tweeted to clarify that he was not injured on the morning of the game in what was seen as a swipe at Sherwood.
After the game, Sherwood told reporters: "I don't care about the tweet. I don't go on Twitter. He can tweet what he wants.
"I like Sandro's qualities, but in my eyes it wasn't right to put him in the squad - other people are ahead of him. I think Nacer Chadli's done well in there and I think Paulinho's done well in there.
"I really don't have a problem with him. He's a good lad. I don't have any problem with anything he's got to say. He's not being disrespectful to me, I don't think."
