Stephen Warnock
Former Liverpool defender on BBC Radio 5 Live

I know local fans will say he was a Liverpool fan in a great Liverpool team, but sometimes players want something else. I respect that.

I really hope he gets a good reception. I think he'll want to put on a show, demonstrate why he's such a talent, why Liverpool's fans loved him so much.

I think the reception will be mixed. I don't think he will be expecting a standing ovation after the way things went, and we have to respect those opinions as well.

I don't think he deserves a mixed reception. He was an incredible servant to the club, but wanted to challenge himself.

Hopefully he gets a great reception.

Trent Alexander-Arnold returns to Liverpool tonight for the first time since moving to Real Madrid, when he will discover if absence has made Anfield hearts grow fonder after the outpouring of ill-feeling that accompanied his decision to leave his boyhood club.

Alexander-Arnold fuelled anger among many Liverpool fans by announcing he was leaving at the end of his contract last summer, with supporters making their fury clear by booing him when he emerged as a substitute in the draw with Arsenal in May.

This was despite the 27-year-old - celebrated in song by the Kop as "the Scouser in our team" - having already played a pivotal role in bringing the Premier League title back to Liverpool.

He is in line to play for Real Madrid in the Champions League match after recovering from the hamstring injury that interrupted his start at the Bernabeu.

Alexander-Arnold will find out if time has healed wounds felt by Liverpool's followers - and will also have the opportunity to show what they have missed as the champions' form has faltered this season.

Slavia Prague midfielder David Doudera says facing Arsenal in the Champions League is "a difficult task" because they are a side with "almost no weaknesses" this season.

The Gunners arrive in Prague having won nine consecutive games in all competitions. of which the last seven have also been clean sheets.

"They have the form and it comes easy to them," said Doudera. "It is very difficult to find anything to surprise them with.

"If you want to attack, they use it to their benefit and they strike.

"I play Fifa with my brother and I buy all the Arsenal players for my team, because they are incredible."

Not everything is going swimmingly for Arsenal, however, with striker Viktor Gyokeres to undergo further tests this week amid fears he has suffered a hamstring injury.

The Sweden international was withdrawn at half-time in the Gunners' victory at Burnley on Saturday having scored the team's opener.

Speaking before the Champions League match against Slavia Prague on Tuesday night, Arsenal boss Mikel Arteta said: "I am concerned because he hasn't had many muscular issues and he needed to leave the pitch and he was feeling something.

"That's obviously never a good sign, especially for a player that is very, very explosive.

"So we are digging in a little bit more to understand where we are in terms of the injury and we'll announce the moment we know."

Good evening!
