Atletico Madrid skipper Koke is under no illusion of the threat Arsenal possess ahead of the UEFA Champions League (UCL) encounter at the Emirates Stadium, London, on Wednesday.

“They have an excellent team, they are really fast on the wings, they have signed a superb striker [Viktor Gyökeres], who I’m sure will score a lot of goals. In my opinion, they are an excellent team, and one of the favourites to win the title,” said Koke while urging his side to be wary.
