It was a frustrating night for Arsenal but one to savour for Manchester United as the two teams posted mixed results in the Europa League quarter-finals first leg fixtures.
At the Emirates, Czech Republic side scored deep into stoppage time to earn the visitors a crucial goal that ensured the tie ended 1-1 against the much fancied Arsenal.
Ivorian Nicolas Pepe had given the Gunners a slender lead in the 86th minute of the game but Tomas Holes poked into the Arsenal defence in the closing moments of the game to give Prague a precious away goal.
The result leaves Arsenal in a very awkward position ahead of the return match to be played next Thursday (10pm EAT)
The Gunners boss Mikel Arteta however believes that there is still hope that they can progress despite the setback.
"The mindset has to be to go there and score goals and win the game because we have to score if we want to go through," said the Spaniard.
"I totally believe that we can go there and win the match, if not I wouldn't be sitting here."
In Spain, Manchester United made light work of La Liga mid table side Granada as they scored a goal in each half to ensure a 2-0 victory ahead of the second leg to be played at the Old Trafford. Marcus Rashford opened the scores in the 31st minute of the game with Bruno Fernandes scoring the second from the spot in the 90th minute.
