The two midfielders struggled to get a grip on the game.
Tottenham Hotspur found themselves put to the sword by an incredible Borussia Dortmund performance last night, as the German side ran rampant in a 3-0 win at Signal Iduna Park.
The German side were much the better team but after the game the team selection of Mauricio Pochettino came in for some scrutiny.
But former Tottenham player and manager Glenn Hoddle does not believe they covered themselves in glory.
He was highly critical of the pair for their role in the second goal Spurs conceded. The pair failed to deal with a short corner from Dortmund and Hoddle told ITV yesterday (10/03/2016) exactly what he thought:
"This was one that Spurs definitely, definitely could have cut out at source. They get caught sleeping on a set play at a corner.
"Mason and Carroll. Carroll has got to go to the ball. The communication from Mason has got to be I've got the runner.
"But they both go with the runner and Carroll for some reason backs away."
Spurs fans will no doubt feel that the side would have coped better with the electric Dortmund style with perhaps Eric Dier and Mousa Dembele in ahead of Carroll and Mason.
But Pochettino clearly has one eye on the Premier League this weekend - with a fixture against Aston Villa at White Hart Lane.
As for Carroll and Mason they simply could not keep up with the Dortmund players throughout the game and were simply found out.
But for the second goal, they should have undoubtedly done better.
