Martin Odegaard appears to have given Arsenal a major boost ahead of their Champions League showdown against Bayern Munich after he was spotted in training on Tuesday morning.

Mikel Arteta put his squad through their paces at the club’s London Colney training ground ahead of their flight to Germany later this afternoon.

The quarter final tie is intriguingly poised after Leandro Trossard’s equalsier ensured a 2-2 draw last week and with away goals no longer a factor, Arsenal will still fancy their chances of progression.

Arteta, however, must raise spirits following Sunday’s devastating defeat against Aston Villa that saw Manchester City taking full control of the Premier League title race.

Odegaard was substituted during the closing stages against Villa with his side desperately searching for a goal that would have broken the deadlock.

Arteta refused to elaborate on the reason for withdrawing his captain and was willing only to reveal he had ‘a leg issue’.

Arsenal’s hopes of pulling off what would be an historic victory at the Allianz Arena will certainly be enhanced as a result of Odegaard’s apparent availability, but they will need to produce a spirited response after last weekend’s morale sapping defeat.

‘‘We’re gutted and disappointed we’ve lost a massive game but, it’s time for a reaction. We’ve been on such an amazing run since January, won so many football matches, and got ourselves back into an unbelievable position after being written off at Christmas,’ said Declan Rice in the aftermath of a seismic setback.

‘‘Now that reaction starts in the Champions League against Bayern, so we’ll be ready for that.We have to park this to the side now. It’s gone, it’s a game of football. We’ve lost but we need to bounce back, that’s for sure.

‘‘It’s a great chance for us to get into a Champions League semi-final. Going to the Allianz Arena, it’s going to be a special night. It’s time to pull our socks up and show everyone why we’re in this position.

‘‘It’s not over yet, there’s six games to go. We’re in an unbelievable position, two points behind.

“We’re still ready, we’re still fully focused on what we want to do and what we can achieve.

‘‘There’s going to be many more twists and turns in the Premier League, I think you can see that with the other results today. Anything can happen and we’ll stay positive.”
