MANCHESTER UNITED and Tottenham fans need to dig deep into their pockets to be at the Europa League final as prices soar. It looks set to be an all-English final in the Spanish city of Bilbao on May 21. United took a 3-0 lead back to Old Trafford for the semi-final second leg after beating Athletic Club last night and Spurs saw off Bodo/Glimt 3-1 ahead of going to Norway. Both clubs have one foot in the final and supporters are researching their trips to Bilbao for the showpiece. But with less than three weeks to the game, the prices of hotels and flights have rocketed. Many places to stay in the city centre have been booked up already and very few remain under £1,000 per night. All direct flights to Bilbao from London and Manchester across the entire week have sold out. The cheapest option to go the day before the game and leave the day after now involves a stop in Milan - though that will still break the bank at around £350. Fans could potentially fly to cities like Madrid and get a train or coach, or they face gruelling drives across Spain after landing elsewhere. United and Spurs fans have been left horrified at the costs, with one saying: "Just looked at hotels in Bilbao. Is there any camp sites near by?"

A third wrote: "Literally stuck between I need to get to Bilbao for the final and my bank account disagreeing with the flight paths." More commented: "Corr flights and hotel priced for Bilbao are crazy for the Europa League final."
