The English manager was in the stands during the game against Blackburn Rovers on Saturday.
The Lions went on to defeat the visitors 2-1 with the goals from Tyrone Mings and Tammy Abraham.
And Villa manager, Dean Smith, reckons Grealish has been watched by Southgate in the prospect of national call-up
Smith said, (h/t Mirror UK)
“Southgate was here, which says a hell of a lot. It will give our English players a boost. I’m sure he will be sending some scouts to watch our games. England knows all about them anyway. It just gives Southgate the chance to come and cast his own eyes on it.”
Smith also lauded Tammy Abraham and Grealish as the standouts of the championship.
“If the talent is drying up in the Premier League then Southgate has to look elsewhere.
Grealish’ recent run has been astounding as he played a key part in leading his side to back-to-back victories. In fact, he scored the winning goal in the Second City derby despite being assaulted by an invader.
The 23-year-old has bagged four goals and five assists this season in more than 20 appearances.
Furthermore, Smith announced Grealish as the new Lions captain on his return from the injury.
Abraham has also been impressive for the Clarets and Blue army scoring a record-breaking 22 goals in this season so far. The on-loan Chelsea striker became the first player to do so in club’s history since 1981.
