Pochettino: Arsenal were competitive with a lot of energy.

Mauricio Pochettino says Arsenal win over Tottenham was due to the fact the Gunners were able to make changes in their midweek Europa League win.

Arsenal came from behind to beat Tottenham in the North London Derby on Sunday in what was an entertaining fixture at the Emirates.

The Gunners broke the deadlock through Pierre Emerick-Aubameyang, who found the net from the penalty spot, before Eric Dier cancelled out the opener with a header.

Spurs then took the lead via Harry Kane from the penalty spot as the Lilywhites went into half-time with the lead.

But in the second half, Unai Emery's side ran riot over their rivals as Aubameyang scored his second of the match, making it 2-2 in the 56th minute.

Alexandre Lacazette's deflected shot put the Gunners in the driving seat before midfield marshall Lucas Torreira put the game to bed with a close range strike making it 4-2, with 13 minutes to go.

After the clash, Pochettino insisted that the Arsenal players were fresher than his players because they were able to rest during midweek before their north London derby on Sunday.

He told Sky Sports: "A very competitive game, tough for us because we were talking before that the fixture, after Chelsea and then Inter Milan, it didn't help with the fixture for us.

"But I think the team was very competitive, Arsenal was competitive with a lot of energy. The game was even until 2-2, when we conceded the third goal for the team it was so tough to come back, to try to be in the game.

"And then when you concede the fourth, and the sending off of Jan Vertonghen, of course the game was over.

"Of course the belief of the opponent, they were so fresh because eight, nine players didn't play on Thursday and they were preparing the game. It is not an excuse but when you concede 3-2 in the second half, you need energy to come back."

Arsenal have scored more second-half goals than any other side in the Premier League this season (24).
