Chelsea made huge mistake over Kevin Oghenetega Tamaraebi Bakumo-Abraham known as Tammy Abraham Tammy Abraham claims Tony Cascarino according to reports in the UK Daily Star.
The talented young forward joined the Swans on a season-long loan in the summer.
However, Swansea are struggling and managerless having axed Paul Clement last week.
They were battered 5-0 by Liverpool at Anfield on Wednesday and offered little throughout the clash.
Cascarino, who played over 600 professional games, reckons Blues bigwigs made a huge mistake letting Abraham move to south Wales.
“Tammy Abraham made a bad call picking Swansea City over Newcastle United or Brighton & Hove Albion,” he wrote in The Times.
“He’s stuck on the bench for a side who don’t create enough chances.
“After a good season at Bristol City with 26 goals he needed a club where he could showcase his ability.
“Under Paul Clement and now Leon Britton Swansea play like a team doing training drills — passing the ball around with little purpose.
