North London outfit Arsenal suffered a major setback in their bid to secure a top-four finish as they were defeated by Crystal Palace on Sunday.
The Unai Emery side still remains fourth in the Premier League table but a win against Crystal Palace could have fired them a step forward to the third position on the log table.
However, there are suggestions that a lot of lessons have been learned by the Gunners boss from the defeat going by his speech in the post-match interview.
The former PSG boss hailed the impressive performance of Crystal Palace stars Wilfred Zaha and Aaron Wan-Bissaka, noting that they are very good players and are still improving in addition to helping their team win games.
Unai Emery hinted that Arsenal could learn from them and he could now have some of his young players promoted to playing in the first team because the club has got a number of them in the academy while others are currently on loan.
Meanwhile, the likes of Emile Smith-Row, Reiss Nelson, Eddie Nketiah, Joe Wallock and a number of them could be seen in the first team ahead of the coming season, especially if they are able to impress and prove their quality in the team.
