It hasn't been an easy few days for Álvaro Morata after the head injury he suffered at Milanello following a hard collision with Strahinja Pavlović.
Thankfully, the worst is now behind him, and everything seems to have returned to normal. He has already played 21 minutes for Spain against Denmark, and tonight he is expected to start against Switzerland.
Alvaro Morata should be fine

Certainly, at Milanello, there had been hopes he could return sooner, especially since Spain has already secured the top spot in their Nations League group. The most important thing, however is that Morata is well and that the worst is definitively over.
This was reported this morning by Tuttosport, which reviewed the recent days of Milan's number 7.
After the collision with Pavlović, the forward spent a night in the hospital and then joined his national team after undergoing routine checks by the Spanish medical staff, who thankfully gave reassuring updates about his condition.
What did Luis De La Fuente say about Alvaro Morata?
Yesterday, the Spanish captain was once again praised by coach Luis de la Fuente:
"I don't know what more he needs to do; he's a great captain and a great person. Morata will leave an important legacy, and we’ll appreciate it over time. He has played for big clubs and won titles, serving as an example for young players. I wish he received more recognition," as relayed via Milannews.it.
Will Morata play against Switzerland?
After playing a portion of the game against Denmark, Morata is expected to start tonight against Switzerland, and he will also be in the starting lineup on Saturday for Milan - Juventus.
