Speaking to STV, Mulgrew admitted that his Celtic teammate Brown doesn’t get the credit for his ability, and is definitely good enough to be playing in English football.
Mulgrew said: “He does all the ugly side of the game which sometimes he doesn't get credit for. But you definitely see it when you play alongside him. Anyone partnering Scott knows the job he does and how valuable he is to this squad.
"He is definitely good enough to be playing somewhere like down south. We've seen it at international and Champions League level what a top-class player he is.”
Brown, who captains both Celtic and Scotland, is well respected for his abilities in his homeland, with his ball-winning abilities and leadership quality a central part of Celtic’s success.
With the Bhoys focused upon playing attacking, technical football under Ronny Deila, there may have been a sense that Brown would lose his place in the team under the Norwegian boss.
However, he has adapted his talents on top of his underlying abilities, and enjoyed a great season at club level.
Mulgrew believes he would be good enough to play in England, and whilst that is a big claim considering the differences in quality between Scottish football and south of the border, Brown has proven himself in the Champions League before.
He may not be of the quality for some of the elite Premier League level teams, but the majority of top flight outfits would improve with a player like Brown amongst their ranks.
He may not get the recognition he deserves due to his under-appreciated play, but there is no denying that he is one of the most important players behind Celtic and Scotland’s success.
