Manchester United great Roy Keane would offer Manchester City his congratulations if Pep Guardiola's side secured a treble this season.
Keane was part of the United side that won the Premier League, FA Cup and Champions League in 1999 and City remain in contention to replicate that achievement. A 3-0 win over Championship side Sheffield United took the Blues into the FA Cup final and Arsenal's failure to beat Southampton in the Premier League on Friday night means City are favourites to lift the title.
Guardiola's men are already into the last four of the Champions League, where they face Real Madrid, for the right to meet either AC Milan or Inter Milan in the final. City's next game is at home to Arsenal in the Premier League in what is being billed as a title showdown and Keane feels it is in Europe where the biggest tests will come for the Blues.
