That's a somewhat unfair justification, IMHO. Madrid is by far our worst opponent, as in the toughest to beat, because their entire game is designed to nullify Barcelona. So, giving Madrid as the example is going over the top. Barca in general has been poor against Madrid this season, and even the likes of Messi and Villa and Iniesta and whoever have failed to do much against them. That's one thing. The other is, as you mentioned yourself, coming in from the bench, especially as late in the game as Tito usually decides, is very different from starting and building up the game from scratch. It's not only the significantly smaller amount of time, it's also about the existing result, the pressure, etc.
All I am saying is that he has done nothing to prove he is the best option against the strong defences - and he has been given chances.
He has proven to be a better choice than both Pedro and Sanchez, for the most part. Yet they have been given many more chances than he has, especially against strong defenses.
Tello outshining them? Sanchez and Pedro have been poor but comparing them to is unfair as he has more or less only scored against the relegation candidates in games won at a canter.
What reason do you believe that Villanova and Guardiola before him did not start him in more of the bigger games?
Before he starts in the bigger games he needs to prove he can make a difference against those teams - he has barely done anything against the well organised teams this season or last.
In what way has he proven to be better choices than Sanchez or Pedro?
One dimensional in a sense that he doesn't have a huge arsenal of technique or skill behind him. He is only good in 1v1's and usually just taps the ball ahead or cuts in. He relies on his speed too much in dribbling and doesn't have much close control or a good first tough so you can't say that he's a very technically sound dribbler. Plus he definitely doesn't have the agility or skills to weave in and out of defenders in multiple directions. Pedro is a pretty good dribbler in a lot of those aspects and Alexis can be (when he is at his best)
The thing that makes Tello one dimensional is that he is very basic and has very standard dribbling options (stop and go, cut in or speed forwards, only dribbling in straightforward 1v1's). He doesn't have the innovative and creative mind to adapt to any situation and improvise skills on the spot to get past 2-3 defenders in multiple directions and different situations (i.e Iniesta, Messi, etc.)
By
1.) scoring equally as many goals as Pedro, and more goals than Alexis, in waaay less minutes (games started/subbed: Tello 9+8, Pedro 20+3, Alexis 14+9)
1.2) having an incomparably better conversion rate than the two
2.) being able to beat his marker and advance towards goal
3.) having better positioning than the two
4.) providing the same work-rate as the two, while being better in every other aspect
When was the last time Pedro and Alexis were able to beat their man in 1 vs 1 situation, those guys are pretty average footballers.I already see star quality in Tello.

I've been thinking it for some time but tonight seems an opportunistic occasion to reiterate ( i missed the game )
Tello is an aggressive winger, very different from Sanchez and Pedro who I don't find that different in skill set. He earned his place and should get at least as much playing time as Villa-Pedro-Sanchez in the near future
