Tottenham encouraged fans to buy virtual tickets for the game and to cement the relationship between the two clubs, have invited representatives to Sunday's third round tie with Morecambe.

This time last year no supporters were present at any of the third-round ties because of a 'stay at home' order for millions in the UK.
While fans will be allowed to attend ties in England, sport in Wales is currently limited to 50 spectators as the Welsh government continues its fight against Covid-19's Omicron variant.
Today's tie between Swansea City and Southampton (17:30 GMT) is being shown live on BBC One Wales and Sunday's match between Cardiff City and Preston North End (14:00) is live on S4C.
Third-and fourth-round replays have been scrapped this season to help with the fixture backlog caused by Covid postponements.
Ties will be played to a finish on the day, with 30 minutes of extra time and penalties to decide the winners if required.
Football Focus is coming live from the home of Kidderminster Harriers.
It's a huge day for the lowest-ranked club left in the FA Cup.
Having entered at the second qualifying round stage on 18 September, Kiddy are looking to make it six wins in the competition this season by beating Championship club Reading.
Alex Scott and guests are on air from Aggborough at 12:00 GMT on BBC One.
From Wolves mascot to FA Cup shock?

The little boy shaking hands with Barnsley captain Neil Redfearn is Russell Penn.
In 1993 Penn was mascot for his boyhood club Wolves - a birthday present to celebrate turning eight.
Fast forward 29 years and Penn is manager of National League North Kidderminster Harriers - from the sixth tier of English football - who are looking to dump Championship strugglers Reading out of the cup at a sold out Aggborough.

'One of the great days in football'
Tony Pulis
Former Stoke manager on BBC Radio 5 Live
When I was managing in the lower leagues, we were always waiting anxiously to pull a big club out in the third round of the FA Cup.
When I got in the Premier League with Stoke, we were hoping and praying we wouldn't get anyone in the lower leagues.
And that is what is special about the third round - it's one of the great Saturdays in football in this country.
I know the FA Cup has gone down the pecking order a little bit but not with the supporters. For the supporters who back their clubs - whatever league they are in - this is a massive day for them.

I'm looking at pictures from Mansfield-Middlesbrough - the first of today's 21 ties.

Perfect conditions for a Cupset.
