Writing for the Liverpool Echo, Aldridge said: "I've kind of known for a while that Trent Alexander-Arnold would be leaving Liverpool. You hear on the grapevine so I expected it, it's just the timing of it coming out.
"So I'm not shocked at all. I know some supporters are angry with him, calling him all sorts, but it's over the top. Fans are fans. Some will see one side, some will see the other side. I'm in between really.
"But it will be interesting to see how he gets on there. I played in Spain for a couple of years. Every day, football papers come out. One bad game you're going to get absolutely annihilated. It's brutal."
