He also lauded them for their transfer business this summer, saying:"This season Arsenal look really good. Winning five games in a row is a great start for the season. They spent the money again this summer and have great players. And as a result, they look great. But I don't think they have exceeded expectations. The team looks strong, players on players."The two-time Premier League winner expects an 'interesting' game at Old Trafford:"Now they face a sterner test against United, even if I think they are favourites as they look better than them. But United have won three games in a row, so it's going to be a really interesting game."Arsenal and Manchester United missed out on the UEFA Champions League last campaign, finishing fifth and sixth respectively. Freddie Ljungberg assesses new Arsenal signing Gabriel JesusThe Gunners roped in Gabriel Jesus from Manchester City for £45 million in July this year to fill a void in offence. The 25-year-old striker has hit the ground running at the Emirates, registering three goals and as many assists in five Premier League games this season.WhoScored.com@WhoScored🥅 Gabriel Jesus has registered the most touches in the opposition penalty area in Europe's top 5 leagues this season (53)40829🥅 Gabriel Jesus has registered the most touches in the opposition penalty area in Europe's top 5 leagues this season (53) https://t.co/iIdcygcJzgWhen asked whether Jesus is one of the best strikers to play for the Gunners, Ljungberg told The Sun:"I don't think we can put Gabriel there yet. But he has the potential and is a very talented young player. This is the first time he has a regular spot; he knows he's going to play week in, week out, which allows him to have some confidence in his game. Let's talk and wait until the end of the season."He added:"That said, Gabriel Jesus looks good but (no, he's not) the best striker since Titi because the club has had some nice strikers since Thierry Henry. But Gabriel Jesus is devastating, and I am looking forward to seeing him this season."Arsenal lost on their last league visit to Old Trafford, losing 3-2 in December last year.
