Armstrong played for Coventry on loan from Newcastle during the 2015-16 season.
The 19-year-old enjoyed a successful season at the Ricoh Arena, scoring as many as 20 goals.
Mowbray has revealed that he wants to bring in the England Under-19 international for a second spell on loan at Coventry.
However, the manager of the League One club has admitted that it will not be easy to sign Armstrong.
“Only Rafa will decide whether he lets him go to another team in the Championship who he doesn’t see as a threat to Newcastle United, or will he send him back to us because it was a good experience and Adam quite liked it and his agent and parents are happy with him coming here because they know he’ll get looked after, and off we go again,” Mowbray told The Coventry Telegraph regarding the prospect of signing Armstrong on loan in the summer transfer window.
“But we have to wait for Newcastle. They know our interest, as they will from 15 or 20 teams interested in him, which is great for them and great for Adam.”
Armstrong is a talented young striker, and he must be praised for the season he had with Coventry in 2015-16.
The striker is not going to find it easy at Newcastle next season, though, as competition for places in the first team will be fierce.
Moreover, the youngster is still ‘unproven’ at the Championship level, and Newcastle manager Rafael Benitez may not see him as a striker who can lead the line from the start of the season.
It would make sense if Armstrong is loaned out back to Coventry again, at least until January next year.
