With Spurs looking forwad to expanding their stadium in the season 2017/2018 means they have to relocate their home games to a different stadium.Wembley stadium was their biggest option alongside with Milton keyes stadium.Due to the number of events wembley holds in a season it will not be possible to have them hold their home matches there.
This leaves them with an option of sharing a stadium with a premier league rival,with Arsenal's emirates stadium being the better option.
