I think his mistake was underestimating his old team’s ability in attack. On retrospect (and definitely from half time onwards) we could’ve played a double pivot DM with Bruno and Sandro to nullify their threat in the attacking half spaces, with Joelinton as CAM who can hold up the ball for an advancing Bruno to lay off for Gordon and Isak or have Gordon/Isak come up short to support him and try to put a through ball behind. Attacking down the wings against them really left us exposed because they kept trying to catch our wing backs out.
