The Croatian and his Besiktas side impressed in several matches against Premier League opposition last season.
New West Ham manager Slaven Bilic played six matches against Premier League opposition while at Besiktas, all of which came in his final season in Istanbul. And from those fixtures, Hammers supporters should be optimistic about what their former player can bring next season.
Though the Turkish giants qualified for the Europa League in the 2013-14 season, Bilic's first at the club, they were ejected from European competition because of the 2011 Turkish sports corruption scandal.
However, the Croatian certainly got his fair share of ties against English opposition last season.
After gaining entry to the Champions League because of Fenerbahce's role in the scandal, Besiktas were drawn against Arsenal in the qualifying round. The Black Eagles drew 0-0 at the Olympic Stadium, and were desperately unlucky to slip to a 1-0 loss at the Emirates that put them into the Europa League.
There, Bilic's side proved their performances against the Gunners weren't a fluke.
Besiktas were drawn in the same group as Tottenham, with both sides having very similar records for much of the stage.
However, in the games against the Londoners, Besiktas came out on top. Firstly, they secured a deserved late draw at White Hart Lane, former Hammer Demba Ba levelling with a penalty but Spurs having to rely on several saves from Hugo Lloris. They then won the return fixture in Turkey 1-0, ensuring top spot in the group.
In the knockout stages, Besiktas would go on to dispatch of Liverpool, who had come down from the Champions League. They initially lost at Anfield, but then won 1-0 in the home tie, and were unlucky to have to go to penalties to win the tie.
Thus, against three of the top six Premier League teams, Bilic boasted a record of two won, two drawn, and two lost. In their corresponding fixtures last season, West Ham won just once, at home to Liverpool, drawing away to Spurs, losing both matches to Arsenal, as well as the home game with Spurs and away match to Liverpool.
Given Bilic's tendency to inspire his team to do well against English opposition, even in the narrow defeats Besiktas suffered last season, and not forgetting the famous 3-2 win at Wembley he inspired Croatia to, West Ham's new season could be a good one.
