Weghorst had three good seasons for Wolfsburg, but this year he's been pretty bad, not just because of the team's performance, his finishing has also been off in terms of xG. I don't know if it's because he wanted to move during the summer, but I'd be weary to spend big on a player, who wants to sign up for relegation in a team like Burnley. In the summer he's 30 years old with 12 months left on his contract, Wolfsburg are more than willing to sell and have already bought (potential) replacements for him, it doesn't sound too ambitious if he takes the first exit to Burnley, rather than waiting another six months to join maybe a top 6 team somewhere.
