West Brom manager Carlos Corberan has admitted that Tom Rogic may struggle for game time after he was left out of the matchday squad entirely against Coventry.

Rogic has failed to become a regular at his new promotion-chasing club after he departed Celtic in the summer.

The Aussie penned just a one-year deal so it remains to be seen if he will stay in the West Midlands beyond the end of the campaign.

Corberan admits Rogic's situation is complex, but he has urged the midfielder to keep working hard as he aims to force his way into the team.

He said: "It's complicated sometimes to give you the answer. I know how good a player Rogic is and how hard it is to leave a player out who could be in the first XI - not just someone who could be on the bench. We can play with a specific number 10, and then a specific 10 on the bench.

"Or, you play with a number 10 and a player who has a different profile, and you don't take two seats on the bench with two players who give you the same. It depends more on this than the player. I can only tell you that to leave Rogic out of the squad is totally unfair on him. Sometimes to leave out another player is unfair for him too.

"When you have a squad with lots of players, you have a problem - you're leaving out good players. When you have a squad without enough good first-team players, you don't have players who can play at the same level if someone is injured. At the end, I think fortunately we have very good players.

"Some players are going to manage difficulties very well, difficulties as a coach for me and for the players, it's all about our journey together. I only can involve 16 outfield players in the team every game, and I have 20 very good players. Four will be out of the group, when they're working well - as they are - it means that every decision you make might be the right one, but it's unfair. This is one of the worst parts for me as a coach - to make unfair decisions."
