PSV coach Ruud Van Nistelrooy believes Arsenal will find it hard to win the Premier League with such a young team.
The average age of the Gunners squad is 23.7 years-old, and the former Man Utd defender thinks it will be a challenge for Mikel Arteta to get a title win with these sets of players.
He said: "The way he [Arteta] is building his team, the way he's letting his team play, the signings he's made to make his team play the way he wants to play and he's connecting it with results.
"And if you are 10 games gone in the Premier League, winning nine of them, you're definitely a contender.
"Obviously it's the youngest team in the Premier League more or less, so that is the challenge."
