Mesut Ozil has backed Arsene Wenger to bring long-awaited success to Arsenal after seeing his work at close hand.
Wenger pulled off something of a coup during the summer when he managed to prise 24-year-old Ozil away from Real Madrid with a £43million bid.
The Germany international has been an instant hit at the Emirates Stadium and has played his part in a flying start to the new campaign by the Gunners, and he is convinced the Frenchman can bring tangible success back to the club.
Ozil said: "He's a super coach. He knows exactly what he wants, he has very definite ideas about where he wants to take his team.
"If we want to be successful, we need that kind of coach."
Ozil will hope for success too on the international stage, and he and his international colleagues will attempt to formally book their trip to next summer's World Cup in Brazil with a Group C victory over the Republic of Ireland in Cologne on Friday night.
The Germans trounced the Republic 6-1 at the Aviva Stadium in October last year, but the Arsenal man has warned his team-mates they cannot take a repeat at the Rhein Energie Stadion for granted.
Ozil said: "We know the Irish team are born fighters and that they give everything until the final whistle to be successful.
"We just have to play our game and I am quite convinced we will deal with this passion if we play to our full potential.
"But the Irish put their foot on the accelerator for the full 90 minutes and they just want to beat Germany."
Fellow midfielder Sami Khedira too knows there is still work to be done and that it would be dangerous to set too great a store by what happened on an astonishing night in Dublin.
He said: "We have positive memories of course. We easily won the game, but that really was down to us playing in a very highly-concentrated way, and that's exactly the way we have to approach this game.
"Ireland are no bad opponent at all. They are a very robust side. They will be fighting for the for 90-plus minutes, and of course they want to make amends for the 6-1 rout they suffered at our hands."
However Khedira is confident that if Germany play to their full potential, there will be no shock result.
He said: "We can be self-assured enough to think it is up to us what the final result will be.
"We will be wanting as quickly as possible to score as many goals as we can so we can be safe in the knowledge that we will finally win it.
"But obviously, they will have little tricks and needles to try to upset us and maybe even score, so we just have to give our all to come away as winners."
