The summer transfer window is open for business and it is expected to be a busy period for Newcastle United.
The Magpies’ hierarchy are keen to build on the momentum gained during an impressive performance during the second half of the Premier league season and add further quality to Eddie Howe’s squad.
Moves for the likes of Lille’s highly-rated Dutch defender Sven Botman and Reims forward Hugo Ekitike are work-in-progress as United look to add to last week’s permanent signing of Aston Villa defender Matt Targett.
There have been numerous eye-catching names linked with a move to Tyneside as the Magpies look to replicate the success of the January transfer window.
But the recent history of the club also suggests that caution is required after previous managers and owners played a part in squandering millions of pounds of signings that failed to make an impact during their time at St James Park.
NewcastleWorld takes a look back at 15 signings that failed to deliver over the last three decades.

13. Yoshinori Muto - £9.5m from Mainz
Very little was known about Muto when he joined in summer 2018 from Mainz. Despite spending three years in the north east, Muto joined Vissel Kobe this summer with supporters still knowing very little about him - save for scoring that goal away at Old Trafford. Photo: Clive Brunskill

14. Christian Bassedas - £4.1m from Velez Sarsfield
Arrived with a big reputation as an Argentina international, Bassedas offered very little during his time on Tyneside and had made just 33 appearances by the time his three-year stay on Tyneside came to an end in March 2003. Photo: Alex Livesey

15. Michael Owen - £17m from Real Madrid
A shock signing and one of United’s most expensive additions of all-time. There were some highs, with a promising start to his time at Newcastle and shining under Kevin Keegan. But injuries, captaining United in their relegation and what seemed an obvious preference for England duty means Owen’s time on Tyneside will not be remembered with any fondness. Photo: Stu Forster
