Frank Lampard fears he may be left out for Chelsea's FA Cup semi-final showdown with Manchester City on Sunday.
The 34-year-old midfielder believes that no player is guaranteed of selection ahead of the last-four clash at Wembley Stadium.
Lampard has played 43 times in all competitions this season, bagging 19 goals in the process.
"I don't think anyone is an automatic selection with the manager at the minute as we see because there are lots of games and he's changing it regularly," Lampard told The Daily Telegraph.
"We're not sure we're playing on Sunday. I'm like everyone else: I want to play every game but it's not possible.
"That depends on how you're playing and what manager you have, and relationships, and things change."
Chelsea are aiming to reach their fourth FA Cup final in the last seven years and are in great form in the competition, having won 23 of their last 28 ties.
Nevertheless, Lampard does not feel that formidable record afford his team an advantage against the 2011 winners.
"I don't think our record gives us an advantage, particularly in a game against Manchester City's quality," he said.
"If they're at their best and we're not, they'll probably win the game and vice versa."
