If you are asking for directions it's not very polite suggesting that Bale and Modric get crocked but i'll help you anyway.
Avoid public transport on a match day, it's better to walk. Turn left when you come out of Euston and walk along Euston Road. Pass St Pancras and Kings Cross and continue up Pentonville Road. At the top of the hill turn left into Islinton High Street and walk for about 200 m where you will see Liverpool Road on your left. Take Liverpool Road. After a short stroll up Liverpool Road you will come to the junction will Holloway Road, turn left. You will soon pass the Emirates Stadium on your right, ignore it and carry on. When you reach the Seven Sisters Road turn right. Continue your brief promenade up the Seven Sisters (you will pass Finsbury Park on your left) until you reach Tottenham. Bear left onto the High Road where you will pass the Seven Sisters Tube Station (what ever you do don't try and use this station, it will be packed full with Spurs fans- very unsafe for away fans). Stroll up the High Road, you will pass Bruce Grove railway station on you left (definitely don't try and use Bruce Grove, it's like the Seven Sisters Tube but far worse) and continue northwards. until you reach Park Lane.....Thats where the away supporters entrance is. If you need a beer just nip back down to Finsbury, its only a short stroll, as away fans are unlikely to be served in Tottenham. Returning to Euston is the same in reverse. Simples...... Alternatively grab a mini cab, get 4 people sharing and it should cost you about £25 a head providing you tell them that you are from Newcastle.
