Swansea City boss Francesco Guidolin has urged his players to quickly get better.
Sunday's 1-0 defeat to Southampton made it three matches without a win for the Swans which has raised some concerns with the Italian.
"I am disappointed. We have to improve as soon as possible, because this way it's difficult to win in the Premier League," he said after the loss at St Mary's.
"I am worried because my job is my job and it is my attitude to be always ready if it's possible.
"Now we have Man City on Wednesday (in the EFL Cup), Man City again on Saturday, and then Liverpool. We have to improve.
"The opponent is not important, but our attitude is."
The loss saw Swansea drop to 15th place on the Premier League table.
