Jagielka has warned Marouane Fellaini he may struggle to get back into the Everton starting line-up after his suspension.
He told the Liverpool Echo: "Felli has been a massive player for us for the first part of the season, but we've done OK while he's been suspended so far which really bodes well.
"The manager knows he has a couple of options he can try and they've worked in the last two games. Victor (Anichebe) has come in and given us that presence up there, Naisy (Steven Naismith) has done really well when he came on.
"Felli is a big talent and when we heard we were losing him for three games we knew it wouldn't be ideal - but at this rate he might struggle to get back in!"
