When a player gains possession for their team after the ball was previously contested or loose. Different from tackles or interceptions - it's about picking up second balls, collecting clearances, and mopping up loose possession. Midfielders who win lots of ball recoveries are often underrated because the stat doesn't get as much attention as tackles or goals but it is vital for gaining control as a team.
N'Golo Kanté consistently ranked among Europe's top players for ball recoveries - his ability to appear everywhere at once and collect second balls made Chelsea's midfield impossible to play through.
Actively seeking to buy a player that is already in the process of joining another club. The hijacking club don't just outbid the first club to make a successful transfer bid, they also convince the player to change their mind when they've already agreed contract terms elsewhere. A hijack creates drama, especially on transfer deadline day, writes headlines, and creates new rivalries.
Manchester United's attempted hijacking of Alexis Sánchez from Manchester City in January 2018 succeeded - Sánchez had seemingly agreed to join City, but United's wage offer was reportedly so much higher that he switched allegiances at the last moment.
