Rafael Benitez has been a revelation at Newcastle United and whilst the Spaniard came in too late last term to help the Magpies avoid relegation, he's revival of the club's fortune this season has put the Tyneside giants back on the route to success.

In the end, if may end up that relegation was the best course of action for Newcastle but all that could be unravelled if Rafael Benitez leaves St James' Park, which will concern fans amidst rumours he's being considered as a replacement for Slaven Bilic at West Ham.

Losing Benitez would be a killer blow for Newcastle and the club need to ensure they have a back-up plan if the former Liverpool and Real Madrid boss is snatched by the Hammers.

Fortunately, there's some great options out there.

With Benitez being high-profile and helping the club's exposure, Newcastle will want similar from a replacement and these two bosses would provide that in abundance....

Jurgen Klinsmann

The German's five-year tenure in charge of the United States national team was brought to a close yesterday amidst the USMNT's poor run of form, but fans should not forget what he has done for 'soccer' in North America.

Popularity of the sport has risen dramatically, particularly following the 2014 World Cup, and Klinsmann also achieved success in the 2013 Gold Cup- not to mention he started Germany's rise to prominence a decade ago after guiding them to the semi-finals of the 2006 World Cup.

At just 52, Klinsmann has plenty of years ahead of him and could enjoy a long journey on Tyneside.

Chris Coleman

Let's face it, it's unlikely Wales will achieve more than they did this summer when they reached the semi-finals of the European Championships.

Of course, qualifying for the World Cup in Russia would be a huge achievement but Chris Coleman's Wales have struggled so far.

He's come a long way since leading Fulham in the early 2000's and his success with Wales will make him a leading candidate for any top jobs within English football that emerge in the next few seasons.

Newcastle would be a huge appointment for him and he has the credentials to be a success.
