Portugal 3-1 Switzerland: 5 Talking Points & Tactical Analysis 

#3 Joao Felix's senior debut verdict: Much to learn

Felix endured a frustrating senior international debut before being replaced after 70 minutes

Benfica wonder kid Joao Felix made his long-awaited senior debut for Portugal on this occasion and within a minute, you could already understand the hype surrounding the teenager's presence.

He almost forced Sommer into a mistake in possession inside the Borussia Monchengladbach goalkeeper's box and instinctively, the crowd could already sense this would be a memorable outing for the 19-year-old.

After all, he has netted 20 goals and created 11 assists in 46 appearances across all competitions. Seemingly all of Europe's big clubs are monitoring his progress and readying huge bids for the forward's signature - not least Premier League champions Manchester City and their cross-city rivals United.

Operating on the left-hand side of a 4-2-2-2 formation alongside Ronaldo in his favored second striker role, he was frequently left isolated and quite frankly struggled. That shouldn't come as much of a surprise given how little he saw of the ball - a game-low 19 touches speaks volumes.

His passing was unconvincing, dispossessed four times and squandered his one real half-chance, firing high and wildly past goal inside the area after Ronaldo's brilliant pass, this wasn't to be his evening.

Replaced for Valencia's Goncalo Guedes with 20 minutes left, he could only watch from the bench as Ronaldo went to work to seal their late victory. Despite all the fanfare and hype he's garnered this season, his debut display is a timely reminder that there's plenty of work left to do and opposition defenders will only wise up.
