Who will have more Grand Slam titles when both are retired?

I think Jack wins at least one but not sure I see him getting to four and beating Murray

Andy... gotta go with the man who has already been there and done it all before!

Genuinely think it might be Jack. Murray undoubtedly the better player as things stand, but winning three or four is achievable!

Murray - But I do think Draper might win one

Would have to go with Murray, as Draper is yet to reach a Grand Slam final!
