Man Utd won yesterday with the plan going by the lines "experience is the key". They had Varane back, they trusted Cavani and Ronaldo up front instead of putting on these Rashford's, Greenwood's, Sancho's, Martial's etc.
That's what experience will do for you. Players knowing how to play the game, knowing how to be a total professionals and taking the responsibilities inside the pitch. Cuads, Morata and Dybala are our experienced players up front/middle, rest are nothing but bunch of individuals. Morata being a workhorse, but the consistency isn't there, while Dybala being inconsistent as well. Cuads is almost the only guaranteed performer there. You can take a look to other teams, like Liverpool with Salah, Mane, Firmino, always responsible in both ways, living the footballing lifestyle and enjoying to play the game. Lewandowski saying he's going to play 5 more years. Man City having their players and demanding system there and Pep to tell, if you ain't showing it, you ain't playing. Barca and RM are in downfall, but in their primes they had players who worked as a team and they all were professionals.
You cannot underestimate the experience and professionalism. You can take a look at the technique, but it's 10% of what the game is and that's usually the thing that gets players signed. We need proper scouting to see, who are the real professionals.
