The Champions League returns this week and Europe's top sides will be looking to get one step closer to last-16 qualification.
Here, we preview the games that will be taking place on Tuesday and Wednesday, and with the help of GIVEMEBET, we give you a few tips along the way.
Tuesday
Group E
Liverpool v Genk
Jurgen Klopp is set to make changes ahead of Liverpool's crucial clash with Manchester City on Sunday. Naby Keita and Alex Oxlade-Chamberlain are in line to start, whilst Mohamed Salah’s place could be under threat as he manages an ankle injury. Divock Origi is likely to come in. Liverpool won the away fixture 4-1 and will be hoping for more of the same on Tuesday.
(GMB odds - Liverpool to win 4-1 14/1)
Napoli v Salzburg
Carlo Ancelotti's side currently top the group with seven points, with the Austrian champions back in third after recording one win and two defeats in their first three matches.
Napoli won 3-2 when these sides met in Austria two weeks ago, with a brace from Dries Mertens and a further strike from Lorenzo Insigne enough to guide them to a second win in Group E.
(GMB odds - Napoli to win & BTTS 31/20)
Group F
Barcelona v Slavia Prague
The Spanish champions have collected seven points from their three group matches to sit top of the section, while Slavia have only managed to collect a single point from their three fixtures thus far. Barca are the overwhelming favourites to triumph on Tuesday night, considering that they have not lost a home game in the Champions League since September 2013.
(GMB odds - Barca to win 5-0 20/1)
Borussia Dortmund v Inter Milan
Jadon Sancho is set to return to the Borussia Dortmund starting line-up for the visit of Inter Milan. Inter are level on four points with Dortmund after three rounds of group fixtures after the Italians were held by Slavia Prague.
It's their superior head-to-head record that puts them above Dortmund in second place behind Group F leaders Barcelona.
Group G
Zenit St Petersberg vs RB Leipzig
RB Leipzig make the trip to Russia to take on Zenit St Petersburg in the Champions League having opened up a two-point advantage at the top of Group G.
The Bundesliga outfit ran out 2-1 victors when the two teams met at the Red Bull Arena on October 23.
(GMB odds - Leipzig to win 2-1 19/2)
Lyon v Benfica
Lyon come into this one having drawn their last six home matches in this competition.
The Portuguese giants prevailed by a 2-1 scoreline when these two clubs met in the reverse fixture last month.
Group H
Chelsea v Ajax
Chelsea are seeking a win which would see them take a huge stride towards the Champions League knockout stages. They started Group H with a home defeat to Valencia, but victories at Lille and then Ajax have see them top the table with six points.
(GMB odds - Chelsea to win 2-1 9/1)
Wednesday
Group A
Real Madrid v Galatasaray
Real Madrid will be looking to make it back-to-back wins over Galatasaray when they welcome the Turkish giants to the Bernabeu in the Champions League on Wednesday night.
Zinedine Zidane's team recorded a 1-0 win over the Istanbul side in their last European game on MD3, which saw them move into second position in Group A behind Paris Saint-Germain.
(GMB odds - Real Madrid to win to zero 21/20)
Paris Saint-Germain v Club Brugge
Paris Saint-Germain will enter Wednesday's Champions League clash with Club Brugge knowing that a win would see them book their spot in the knockout round of the competition with two games to spare.
The French champions have picked up nine points from their three Group A fixtures thus far, meaning that another victory against third-placed Brugge would see them qualify for the last-16 stage of the tournament.
(GMB odds - PSG to win 5-0 17/1)
Group B
Red Star v Tottenham Hotspur
Red Star will attempt to recover from a heavy defeat at Tottenham as the teams meet again in Belgrade.
Spurs were 5-0 winners in north London on matchday 3; Heung-Min Son and Harry Kane both scoring twice and Erik Lamela getting the other as Red Star made it five away defeats from five matches in the UEFA Champions League group stage.
(GMB odds - Spurs to win to zero 41/20)
Bayern Munich v Olympiakos
It’s top versus bottom in UEFA Champions League Group B when Greek champions Olympiakos visit the Allianz Arena in Munich.
Bayern Munich have all-but qualified for the knockout stages with three wins from their opening three games, but for the Greeks there is a long tough road ahead if they are to make the top two.
(GMB odds - Munich to win 3-0 37/4)
Group C
Atalanta v Manchester City
Free-scoring Manchester City have hit 10 goals in winning their first three Group C games and now visit point-less Atalanta.
City will aim to make it four wins out of four – and clinch a place in the knockout stages – at Atalanta, whose debut UEFA Champions League campaign has featured three defeats to date.
(GMB odds - City to win & BTTS 23/20)
Dinamo Zagreb v Shaktar Donetsk
A matchday 3 draw in Ukraine kept Dinamo Zagreb and Shakhtar Donetsk level on points in Group C, and they now resume their rivalry in Zagreb for a potentially pivotal encounter.
Dinamo are unbeaten in nine home European fixtures (W7 D2). Shakhtar have won only two of their last 10 UEFA Champions League matches (D4 L4).
(GMB odds - Dinamo to win 5/4)
Group D
Bayer Leverkusen v Atletico Madrid
Atletico Madrid inflicted a third Group D loss on Bayer Leverkusen in Spain, and a repeat in Germany would eliminate their hosts.
A tight matchday 3 fixture in Spain was settled in the home side's favour by an Alvaro Morata goal 12 minutes from time, giving Atletico seven points from their first three fixtures, level with Juventus – and seven ahead of a Leverkusen side who have lost every game, scored just one goal and trail third-placed Lokomotiv Moskva by three points.
(GMB odds - Atletico to win 1-0 31/4)
Lokomotiv Moscow v Juventus
Italian champions Juventus will be looking to make it back-to-back wins over Lokomotiv Moscow when they travel to Russia in the Champions League on Wednesday night.
Maurizio Sarri's side recorded a 2-1 victory in the reserve match to move onto seven points in Group D, leaving Lokomotiv with just three points to show from their three games in the section. The Moscow giants are third in Group D with three points, four points off second-placed Atletico Madrid and leaders Juve, who both have seven points to show from their two matches in the section.
