Answer
Bolton Wanderers acquired Gary Cahill for £5 million. Cahill, a promising young defender, joined Bolton from Aston Villa in 2008. He quickly established himself as a key player for the Trotters, making over 100 appearances and helping the club reach the 2011 FA Cup semi-final. Cahill's impressive performances earned him a move to Chelsea in 2012, where he won multiple major trophies, including the Premier League and Champions League.
