15 Newcastle United signings that failed to hit the heights at St James's Park - including £14m flop

There have been some big-name signings that have not lived up to expectations during their time at Newcastle United.

Newcastle United are aiming to add to their squad during the January transfer window as they look to strengthen Eddie Howe’s squad and build on the unquestionable momentum built up over the last month.

As it stands, the Magpies are in the race for a Champions League place, hold a two-goal lead after the first leg of their Carabao Cup semi-final against Arsenal and get their FA Cup run underway with a home tie against League Two club Bromley on Sunday afternoon.

With their battle against the Premier League’s profit and sustainability regulations still ongoing, there is little room for error in the transfer market - and the current Magpies hierarchy will hope to avoid repeating some of the costly mistakes made by the club throughout the last 25 years.

With the midway point of the January transfer window rapidly approaching, we take a look at some Magpies signings that have failed to hit the heights during their time at St James Park.
