Rosenior is under immense pressure with Cheslea losing four consecutive games across all competitions for the first time since 1993.
Chelsea looked clueless in their 3-0 defeat to Everton, seriously denting their chances of qualifying for next season’s Champions League.
Speaking to reporters after the game, Rosenior admitted the performance was “disappointing,” but insisted his side had chances.
“The most disappointing evening so far. In terms of the things we spoke about, not gifting goals away, getting control of the game - it wasn't there," he said.
“For me, we arrived in the final third a lot. We had an edgy start and then managed to gain control of the game but we weren't clinical enough.
“Out of nowhere, they score - and that's not the first time that has happened. We came out in the second half, had control of the game and made a mistake and we were 2-0 down.”
