It was such a dumb tackle, there didn't seem to be any malice to it, just pure stupidity.
Thought there was clear malice in it tbh, followed through on the knee when he easily could have pulled out of the challenge
Seen replays now four times and don't see what you mean by follow through.
When he touched the ball he could have pulled back his leg but instead he continued to bring it forward straight onto Messi's knee
