Dani Carvajal asked David de Gea for help as the Spain star sent a classy get-well message to England crock Luke Shaw.
Left-back Shaw was knocked out when his head thudded to the floor sickeningly after an aerial clash with Carvajal in England’s 2-1 Uefa Nations League win.
Players and Wembley fans looked on in alarm as Shaw, 23, was given oxygen and lengthy treatment on the pitch, before having a precautionary X-ray the next morning.
Spain right-back Carvajal, 26, tried in vain to find Shaw after Saturday’s tie.
The Real Madrid star went into the England dressing room but Shaw was being treated elsewhere.
So Carvajal asked Spain keeper De Gea for the phone number of his Manchester United team-mate.
Carvajal then texted Shaw, who has also seen supportive tweets from others players, including Spain skipper Sergio Ramos and England scorer Marcus Rashford.
Real centre-back Ramos simply said: “Get well soon.”
And Shaw’s club-mate Rashford, whose opener was teed up by Shaw, posted: “What a ball by @LukeShaw23, really hope your alright pal.”
Shaw himself tweeted barely an hour after his injury to say: “Thank you for all the love and support I am doing fine and am in the best hands. I’m a fighter so I will be back soon!”

Meanwhile, Jordan Henderson admitted the Three Lions “feared the worst” when they saw the aftermath of Shaw’s horror fall.
Liverpool’s England midfielder Henderson said: “I wasn’t very close at the time but I’ve seen his head sort of shook.
“I think he is OK, back in there now. At first I didn’t know how serious it was, but obviously when the paramedics come on with the stretcher and the neck brace you start to fear the worst.”
Shaw will return to United on Monday as he recovers from his KO.
