Southampton boss Ronald Koeman is unsure how they can improve on this season.

Saints can qualify for the Europa League with a result at Manchester City tomorrow.

"That's very difficult to improve on. It's more difficult to push up now than from 14th to eighth position in the table because we are fighting bigger teams who normally have more money to spend," Koeman said.

"This season for Southampton has been incredible. One point behind Tottenham, two points behind Liverpool and to make the next step, I don't say it's impossible, but it's very, very difficult."
