It is safe to say that Tottenham Hotspur fans revel in Arsenal's misery, and the same goes for some former players.Graham Roberts, who played in defence for Spurs between 1980 and 1986, is one of those ex-professionals who rather enjoys poking fun at the Gunners.On Thursday night, Arsene Wenger's men took on little-known Swedish side Ostersunds in the second leg of their last-32 Europa League tie.The Gunners had a 3-0 advantage from the first leg, but they suffered disappointment at the Emirates as they were beaten 2-1 on the night.Hosam Aiesh and Ken Sema stunned the home crowd by going two goals to the good within two minutes of each other in the first half.Sead Kolasinac managed to pull one back for Arsenal, but they ended up on the losing side.[ad_pod ]Despite the result, the North London outfit progressed into the last 16 stage of the competition.It was difficult to ignore the outcome of the game, and Roberts rubbed salt into Arsenal's wounds by launching a dig at Wenger.Many supporters wanted the manager to call time on his two-decade tenure last season, but the Frenchman ended up signing a new two-year contract.With results like these, the likes of Roberts and his fellow Tottenham fans want Wenger to remain at the helm for as long as possible.
