Five who jumped the Black Country divide
Bakary Sako is the latest threatening to take the barely-trodden path between Wolves to the Hawthorns and West Brom.
It would break the hearts of many of his former adoring supporters. Here,
looks at five other players who have crossed the Black Country divide.
1 Ally Robertson
Scottish centre-half Robertson represented Albion for 17 years and made more than 500 appearances for the Baggies.
He enjoyed a four-year spell at Molineux after leaving Albion and won back-to-back promotions as Wolves climbed from Division Four to Division Two.
The defender also captained Wolves to a Wembley victory in the 1988 Sherpa Van Trophy.
2 Steve Bull
Tipton-born Bully rose to prominence firing in shedloads of goals for non-league Tipton Town and leaving school and working multiple manual labour roles at the same time.
He got his break at the Hawthorns in 1985 but only made three league appearances, scoring two goals.
It was at Molineux where the Wolves legend really honed his talents, as he bagged a club-record 306 goals while also notching up 13 England caps.
3 Danny Hegan
Midfielder Hegan began his career with Albion Rovers before moving south to Sunderland and settling at Ipswich Town in at the 1960s.
More than 200 appearances followed for the Tractor Boys and six years at Portman Road was followed by a Midlands move.
The talented midfielder could only muster little more than a dozen appearances in his one season at the Hawthorns, before jumping ship to Wolves the following summer.
He spent three years at Molineux and was involved in their run to the 1972 UEFA Cup final.
4 Bobby Gould
The striker had profitable spells with home-town club Coventry City and Arsenal, before his move to Wolves in 1970 for £55,000.
His decent return at Molineux tempted Albion boss Don Howie to lodge a bid of £66,666.
A goal ratio of around one in three followed Gould around his career, but performances at Albion began to dip and a move to Bristol City signalled the end of his Hawthorns career.
Gould returned to Wolves in 1975, where he scored a further 13 times.
5 Andy Thompson
Featherstone-born full-back Thompson was involved in the £65,000 deal that took Albion team-mate Steve Bull to Molineux.
After 24 appearance for the Baggies in the 1985-86 season, Thompson went on to play almost 451 times in the gold and black of Wolves.
A vital part of Wolves' double-promotion in the late 1980s, he also remained a reliable performer into the next decade.
