Wales coach Ryan Giggs admits he refuses to consider the prospect of Manchester City winning the Quadruple.
Giggs was part of Manchester United's 1999 Treble winners.
And on City, he smiled: “I've got enough to worry about – please don't bring that up.
“They (City) are a fantastic team and they have obviously already got one. United going out of the FA Cup makes it a little bit easier for them.
“They have a long way to go, and just like us in the Treble, you need a bit of luck and a lot of things to go for you, which they had at the weekend.
“They're a brilliant team and it will be interesting to see what they can achieve."
