Arsenal continued their incredible winning run on Thursday night with a 1-0 win away at Sporting in the Europa League.Danny Welbeck got the goal on this occasion as the Gunners recorded an eleventh straight win - their best run in over a decade.It was a great defensive performance by Unai Emery's side, dominating possession and limiting Sporting to precisely zero shots on target.Things certainly look incredibly promising right now and any fears that there would be a considerable adjustment period after Arsene Wenger's two-decade-long spell have been firmly dispelled.Back-to-back defeats at the start of the season to Manchester City and Chelsea had initially suggested that Emery had his work cut out for him - only for him to guide his side to victories in every game since.But it's not just results that have brought the manager credit as his signings have, too, with Lucas Torreira getting particular acclaim.The Uruguayan started on the bench against Sporting but he was eventually subbed on after 58 minutes.And his resulting impact was enough to unite Arsenal fans in an opinion: that the 22-year-old might be the most important player at the club.Welbeck's goal was the result of a pass from Torreira that Sebastian Coates failed to stop but his all-around game and impact on the side really caught the eyes of the supporters.You can check out their reaction below:

It's obviously very high praise for the 22-year-old, given both his age and the fact he's only been at the club a few months.

Even more remarkable is that Arsenal secured a player of such incredible potential for just £26m - if he truly is the player the fans think, he's got to be a strong contender the for signing of the season.

His Arsenal career is still young but it does look like the Gunners have got a very special player in Torreira.
