In our Transfers that shook the club feature, Football Transfer Tavern takes a look at deals that many may not have seen coming and the impact that they had during their time by using statistical data and pundit remarks.

Kevin Keegan is a name that makes the hairs stand up on the necks of Newcastle United fans around the world.

A fine player for the Magpies, the now 69-year old scored a rather impressive 48 goals in 78 games in English league football between 1982 and 1984, according to Soccerbase.

Many supporters of the Tyneside club would have therefore relished the appointment of Keegan as manager ahead of the 1993/94 season, when he won 24 of his 43 matches in carge, with his team scoring 89 goals in the process, as per Transfermarkt.

The 1994/95 season would see his record dip slightly, as the Englishman won 23 of his 47 games as coach, with his side managing to score nine fewer goals (via Transfermarkt).

However, it was arguably not until the 1995/96 campaign that Keegan really made his mark. Finishing just a mere four points off of Sir Alex Ferguson's Manchester United in the Premier League table, the Geordie guided his team to a quite respectable second place. On the other hand, this could remarkably be seen as an ultimate failure, with the Magpies being 12 points clear at the top of the table in February.

Ultimately, Keegan's tenure at St. James' Park came to an end in the January of the following year, as the Toon Army still ponder what might have been.

However, little did they know back then that this was not the end of the Messiah. Indeed, the silver fox returned as manager in the northeast in January 2008 in what may have come as a shock.

Unfortunately, Keegan only managed to win four out of his 17 games in charge during his second spell in charge (per resigning after only eight months in the job, which left the club searching for a new boss very early in the campaign.

With all of this in mind, it cannot really be said that the return of King Kev was all that successful, and so fans may still be cursing their luck that his reign could be deemed ultimately as another failure, with flashbacks of the 1995/96 Premier League title collapse still fresh in their minds.
