That is not true. The tram service this year has been far better this season than recent years. Still not perfect but getting there. It just needs a bit of planning by those in charge to put enough trams in place after the end of the match.
Some if these comment here are hilarious. The suggestions to build monorail, elevated transport systems, heavy rail lines all to transport people 1.5 miles from and to the City Centre for (generally) less than 30 match days a year over a four to five hour period do not stack up.
