Arsene Wenger insists that he is still nervous before every game as he has no clue what the future holds Getty

Arsene Wenger has revealed that he did not expect Arsenal to go on an eight game winning streak in the league and that it was down to the lack of injuries and greater balance in the squad.

The Gunners have not lost or drawn a game after their 2-1 loss to Tottenham in White Hart Lane in February and their only other loss this year came on New Year's Day against Southampton when they had a dilapidated squad owing to injuries.

The run has kept the difference at the top of the table to seven points and their position to second in the table, one point ahead of Manchester United and five ahead of Manchester City.

The Frenchman finally has hit upon a winning solution with Mesut Ozil, Francis Coquelin and Santi Cazorla in midfield while Aaron Ramsey has been deployed on the wings to add more stability in the middle of the park.

The move worked well against Burnley when the Welshman scored the winner in the 12th minute to secure their eighth straight win in the league, the longest run in the division. However, he agrees that it was difficult to predict this run and in spite of all the preparation there was a lot of luck involved in the process.

"I always hope to get the best out of my team, but no manager in the world if he is serious can predict a run like this. In the Premier League it's very difficult to predict," Wenger told Arsenal's official website.

"It's down to the quality of the attitude of the team, the quality of the spirit we have in the side.

"We prepare [well], we prepare and contribute to our success, that is for sure. What people forgot is that we had big players out for four months this season. Six or seven players from the squad completely out. So that made a big difference.

"We have a better balance in the team and some players have made it like Coquelin, who contributes to the balance of the team. Hector Bellerin as well has come into the team. And big players like Koscielny, like Ozil, like Giroud have been out four months in the season - four months the three together!

"I have a quality bench and we even have quality players at home like Chamberlain, Arteta, Wilshere. I didn't even try [to play] Debuchy. We have a big squad and I think we have quality. Let's see how we finish the season and after see how we do next season."
