The 26-year-old Colombia international is making his Premier League debut for Arsenal today.

He joined the club from Nice in the summer after impressing at the World Cup in Brazil where he was part of the Colombia side which reached the quarter-finals.

This is his third start for Arsenal having only appeared in the FA Cup and League Cup so far, as well as a substitute appearance against Galatasaray in the Champions League in October after Wojciech Szczesny had been sent off.

A change of his shirt and Nacho Monreal is good to go again. Stoke then come forward as Geoff Cameron curls a teasing cross into the area, but Arsenal clear before Erik Pieters' ball back into the box is caught by David Ospina.

"A number of Arsenal fans sat in front of us here in the press box very unhappy with Stoke manger Mark Hughes and the nature of some of the tough tackles that have been going in from his players."

A pause in play as Nacho Monreal takes a whack from the arm of Peter Crouch as both players jump for the ball. No chance that was an intentional Elbow, he is more of a Kasabian man anyway.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "It's wonderful play and lovely interchange between Rosicky and Sanchez. I thought he would bend the shot round, so I've no idea how he snuck it in at the near post. It underlines the quality of the player."

Well that is just brilliant! Alexis Sanchez, who else, slots in a cheeky second for Arsenal. The forward runs on to a pass from Tomas Rosicky, scampers into the area and just as every watching person is expecting him to try and break past Ryan Shawcross he somehow manages to clip the ball into the net at the near post. Asmir Begovic knew nothing about it until he was picking the ball up out of the net.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "These Arsenal players should have signs around them saying 'Do not touch'. It's ridiculous, the fans are up for everything."

Rob: Arsenal just aren't clinical like what we saw from Chelsea yesterday. Always go into the last 10 minutes with a one-goal lead and we all know how Arsenal deal with pressure...

Tomas Rosicky is on the receiving end of a hefty challenge by Marko Arnautovic midway inside the Stoke half and Arsene Wenger, along with the home crowd, calls for a booking. Referee is keeping his cards in his pocket for now though.

Tommo: Arsenal fans deluded if they think that subs bench is quality. Washed up keeper and CM, no decent defender and a striker who is so good, he's only made 4 Premiership appearances this season.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "From an Arsenal point of view, I can't understand how they didn't see what Stoke were going to do. The space for the pull-back was unbelievable and Glenn Whelan should have done better."

A free-kick routine forged on the training ground almost catches out Arsenal as Bojan, on the right side of the area, sweeps the ball low to Glenn Whelan, who races in unmarked to the edge of the box, but smashes the ball well over.

A rare foray into Arsenal's half for Stoke as they win a free-kick, Glenn Whelan pumps it into the box for Ryan Shawcross but the defender can't quite reach it. Erik Pieters' cross then takes a slight deflection, almost wrong-footing David Ospina, but the Arsenal keeper manages to smother the ball before any Stoke players sneak in.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "Inside 21 minutes, Asmir has pulled off three fantastic saves. The latest one was world-class. Stoke are going through a bumpy time at the moment."

Asmir Begovic is keeping Stoke in this as a hungry Arsenal side come forward again, this time Begovic flings himself to his right to push away Olivier Giroud's thumping effort. Moments later, Giroud beats the offside trap but lashes a shot well wide.

Former Stoke captain Andy Griffin on BBC Radio Stoke: "As soon as you lose possession, you have to get behind the ball and get back into position. Stoke need to make it harder for Arsenal to get through."

Alex Oxlade-Chamberlain returns to his original position following Hector Bellerin's introduction and almost grabs Arsenal's second, getting the better of Erik Pieters on the edge of the area with some fancy footwork before firing just wide.

Mathieu Debuchy, meanwhile, is sitting up, clutching his shoulder before he is lifted onto the stretcher and taken away to applause from the Stoke and Arsenal fans.

This is not nice to see. Mathieu Debuchy, who has already missed three months of the season with an ankle injury, is still receiving treatment with a host of medical staff and a stretcher alongside him. He cannot carry on and Hector Bellerin is on to replace him.

Concern for Arsenal now as Mathieu Debuchy is down injured by the advertising hoardings after tangling with Marko Arnautovic on the edge of the pitch. The Gunners are temporarily down to 10 men while Debuchy is treated, Alex Oxlade-Chamberlain dropping into his position for now.

Fans at Emirates Stadium have paid tribute to the victims of the recent terrorist attacks in the Paris area by holding up signs saying "Je Suis Charlie".

The players of both teams are also wearing black armbands. Five of the Arsenal players are French, with their compatriot Steven Nzonzi in the Stoke side.
