The 2 videos above are great to show how good and underappreciated he is. Some of the stuff people have said bashing the guy is mind boggling. Just a very solid player. One thing you notice in the videos is that he needs to shoot more. When he's made it past the midfield and is approaching the other team's box, the defenders in front of him are collapsing and trying to cover our other players while giving Matip plenty of space in front of him to shoot. His passes through the middle that basically bypass the entire midfield are also fantastic.
