Marco Silva may never have to buy himself another pint in Hull again, but what about his earlier career?

Prior to his move to England, the Portuguese manager was little known on these shores but could point to successes at both Olympiakos and Sporting Lisbon, having won trophies at both despite spending only a season with either club.

He left the Greek champions only a year ago, having secured the SuperLeague title by a mammoth 30-point margin, citing 'personal reasons' for his departure.

And his brief reign in south Europe is the focus of the final part of our look at the new Watford head coach:

As a man who doesn't tend to stick around, Watford might have found their perfect man in the shape of new head coach Silva.

While his departure from Hull was inevitable following the club's relegation, his resignation as Olympiakos boss - where he had just secured the Greek league title by a record tally - was far more perplexing.

A 30-point gap to second place was, by some margin, the largest since the country's football association began awarding three points for a win in 1992.

Internationally, too, Silva had enjoyed success with the club - securing a famous victory against Arsenal at the Emirates in the Champions League, before narrowly missing out on qualifcation, and losing to Anderlecht in extra time of the Europa League last-32.

Watford Observer:

On the surface, it seemed another season of success for Silva. So where did cracks begin to surface before his resignation?

"He was still certain to continue as the Olympiakos manager for at least one more year, but it was suddenly announced last June that he was leaving with immediate effect," George Georgakopoulos, sports columnist at Greek newspaper Kathimerini said.

"At the time it was thought this was because he might join a club in Portugal, but it later emerged he had clashed with senior Olympiakos executives over the club's budget.

"His departure left a gap that one year on Olympiakos has not yet fulfilled, as the club has hired and sacked four managers in the last 12 months."

But while Silva's presence has been difficult to replace in Athens, it wasn't always plain sailing, even for a side coasting to its 43rd domestic title.

It's difficult to be picky when a team drops only five points in the course of a season.

However, having won each of their first 17 league games, the second half of the season was less profitable when it truly mattered - with a surprise exit from the Europa League to Anderlecht, and defeat both in the league and Greek FA Cup final to AEK Athens.

"Having bagged the title so early and got demoralized by the exit from the Champions League, Olympiakos succumbed to an inferior Anderlecht in the Europa League and dropped some points, albeit a few," said Georgakopoulos.

"Silva was clearly unable to motivate his players ahead of the Greek Cup final against AEK (which got postponed twice for security reasons) and saw his team suffer a comprehensive loss in that final that put a damper on his stint here.

Watford Observer:

"It might be his motivational tactics were not up to scratch but in context of the league, which was quite strange at the time off the field, I can understand why he may have found it hard to galvanise his players.

"But crucially, under Silva Olympiakos played a very attractive type of football that was attack-minded, provided fans with plenty of goals and excitement and had its opponents scratching their heads over how to deal with the Reds."

In much the same high regard as he was held in at Hull, Silva grew his popularity through engagement with fans in Greece and was always happy to talk to the media.

The reputation he built meant a year on, his appointment as Watford manager still garnered major press coverage in south Europe, despite having taken Hull out of the Premier League only days before.

"His move to Watford was also big in the Greek press, but his relegation with Hull, especially the home loss to Sunderland, put a bit of strain on his fame in this country," Georgakopoulos admitted.

"When he got hired by Hull there was a very positive coverage of him in Greece - as far as if he were a Greek coach.

"Silva was a devoted professional who was very media-friendly, especially given the limitations imposed by Olympiakos, and he left a very good impression with the Greek press as well as the fans.

"He was eager to answer questions and to explain anything related to football. He was not so keen on answering personal questions though, which was fair enough."
