Arsenal really tried their best in the Champions League competition last season, although it is true that Bayern Munich beat them with experience. If not Arsenal, we’re doing very well last season, but next season they will do even better in the Champions League since they already have the experience. I can’t predict, but I can give them hope for winning the trophy next season.
Since they got to the quarterfinals last season, they will definitely win the trophy next season. We should be expecting more from them. I’m expecting Arsenal to comeback with a better performance that will give them a trophy next season, both in the Champions League and Premier League.
The trouble is that being able to go for three titles at the same time is nearly impossible, most teams give up on FA cup first of course, so lets assume two. You need experience along with talent, and you need a deep squad.
You can definitely buy your way into a deep squad if you want to, but you also need all of those people to have some experience, so if you want to win a title, you need to get people who already got title, not the whole squad but a few of them would benefit a lot. Right now, Arsenal failed to win the title for many years now, and they failed to get UCL too, so that means, they do not have that experience right now and each time they try, they reach what their talent can bring, but when experience matters, they fail.
