Everton manager Sean Dyche insists he's facing many selection issues at the club.
The former Burnley coach has revived the Goodison Park club in recent weeks.
Dyche, however, admits that choosing central defenders has been tough for him in recent matches.
Summer arrivals James Tarkowski and Conor Coady have been first choice most of the season, but Michael Keane earned a chance to play in a 1-0 win over Brentford this past weekend.
Post-game, Dyche said: I don't know what year we're at now, is it six years he's been here? Seamus has been 14, and people were pointing out the ups and downs he's had.
The longer you're at a club, it's difficult not to have those periods. And it's how you respond.
People maybe questioned me about putting him back in, and these are decisions you have to make as a manager, and I can assure you they're not always easy decisions.
Conor (Coady) was playing, fine professional that he is, you can only play 11. And so Keano came in.
There were questions about the game at Arsenal, but I said you've got to get fit, you've got to get that sharpness from somewhere, and I thought he did really well at Forest. The margins between these players at the moment, they are all working so hard and putting everything in, and so the decisions are hard."
