Tottenham boss Jose Mourinho insists he's unconcerned over the prospect of Lionel Messi joining Manchester City.

Spurs defeated City on Saturday to go top of the Premier League table.

The win was achieved 24 hours after City manager Pep Guardiola had signed a new deal to 2023 amid reports of Barcelona superstar Messi also being lined up.

Asked about the prospect, Mourinho waved the question away.

"A departure of Lionel Messi to Manchester City? I have no idea," was all he would say.
