My issue with Bruce is, as proved many times in the past.. Is say Maloney has a stormer against Arsenal tomorrow, or Maguire for example... will Bruce have them starting the next league game? No, he'll stick with the usual first 11.. He always says "this is a time for players to impress" but very rarely have I seen him actually put that into action.
Jak's performance is the perfect example, he had his best game for us, possibly his best game in his career and for me, why not let him in the next game against Ipswich?
Im not saying everytime a player has a great game, chop & switch the team up for the sake of it. But what is he showing the players by not including them in a league game when they've thoroughly impressed in the cup..
Tymon is another example, although he's young, he was great against Arsenal... so why not let him start at left back and push Robertson into the left wing role where Clucas has been under performing recently..
You just get the idea that Bruce has his mind made up about who will play and no matter who really shines in the cup, they've got very little chance of starting a league game.
