With the 2026/27 Champions League group stage officially getting underway in midweek, we have a stacked Tuesday schedule from across the continent.As 15-time European champions Real Madrid welcome Inter Milan to the Spanish capital, the likes of Manchester City will also steal centre stage.For those of you looking to stick on a midweek accumulator, we have taken an in-depth look at some of Tuesday’s most attractive Champions League betting tips.Tuesday, September 8thBST 20:00 Real Madrid vs Inter Milan While Real Madrid might have appeared to be enjoying life under a returning Jose Mourinho, Los Blancos certainly were handed a rude awakening over the weekend.Watching their early flurry come to an abrupt end as they slumped to a toothless 1-0 loss away at Real Betis on Friday night, the former Manchester United boss will be demanding an immediate response here.Getting their Champions League adventure underway on Tuesday night, the 15-time European champions will be desperate to lay down a heavyweight marker.Last seen in the Spanish capital cruising their way to a routine 4-0 romp against La Liga newcomers Malaga, Real Madrid have suffered just a sole competitive defeat in front of their own supporters since the start of March.Likewise, Mourinho’s men clinched a 2-0 win when they last welcomed Inter Milan to the Bernabeu back in December 2021 and they have won also all of their previous four consecutive Champions League battles against Tuesday’s guests by an aggregate score of 8-2.Mounting what will be remembered as an all-time comeback on Saturday evening as they dragged themselves to a stunning 3-2 victory at home against bitter domestic rivals Napoli, Inter Milan certainly find the mood in their camp at a red-hot high.Recapturing their Serie A crown at a canter last season, Cristian Chivu’s men have further established themselves as Italy’s ultimate poster boys.Winning all of their opening three Serie A appearances and almost universally regarded as the standout contender to defend their domestic title this year, Inter Milan should also be excited by their rugged success on the road.Suffering just a sole away defeat since their Champions League exit and the hands of Bodo/Glimt back in February, Chivu’s side could be smelling the chance to lay down a famous European marker here.However, it should be highlighted, the Nerazzurri could only muster a sole clean sheet from any of their final seven Champions League matchups last season.Betting Tip: Both teams to score @ 8/11 1xBet20:00 Porto vs Manchester City While Manchester City might have opened Enzo Maresca’s tenure with a nightmare 3-0 Community Shield drumming against Arsenal on August 16th, the Sky Blues have come roaring back in an eye-catching fashion.Mounting a sensational last-gasp comeback at home against Bournemouth on the opening weekend as they claimed a 2-1 victory, the former Chelsea boss has seen his new squad win each of their first three Premier League appearances.With their sights set on mounting a genuine domestic title charge this year, Man City should also be excited by a dominant record against Tuesday’s hosts.Despite being forced to settle for a 0-0 stalemate when they last travelled to Portugal for a Champions League showdown back in December 2020, Maresca’s side are unbeaten in all of their four historic battles (three wins, one draw).However, only making it to the Round of 16 during last season’s tournament before they slumped to a 5-1 aggregate defeat against Real Madrid, City could face a tricky European opener here.Crowned Portuguese champions for the first time since back in 2022 last season, Porto have once again embarked on a dominant start to proceedings.Almost universally regarded as the standout contender to defend their domestic crown this year, the Dragons will be relishing a heavyweight Champions League opener on Tuesday night.Last seen over the weekend clinching a 2-1 victory at home against Moreirense, Francesco Farioli’s men find the mood in their camp at a red-hot high and they have rightfully received plenty of plaudits.In fact, Porto have won all of their opening five Primeira Liga appearances by an aggregate score of 11-1 and they already hold a five-point buffer over the chasing pack.Flying out of the traps since opening up the 2026/27 campaign, Tuesday’s hosts have also not suffered a single defeat in front of their own supporters over the past nine months.Betting Tip: Josko Gvardiol over 0.5 fouls @ 1/2 BetUS20:00 Borussia Dortmund vs Villarreal Although Borussia Dortmund might have been hit with Super Cup heartbreak on August 22nd as they slumped to a 2-1 loss against arch-rivals Bayern Munich, Niko Kovac’s side haven’t shown any signs of a hangover.Putting in an action-packed display over the weekend as they secured a thrilling 3-2 victory away at Hoffenheim, BVB should find the mood in their camp at a real high.Getting their Bundesliga charge underway with a routine 2-0 win against Hamburger last month, the German giants have also impressed with their clinical performances in the final third.Extending on their DFP Pokal adventure with a 5-0 romp away at fifth-tier outfit HEBC Hamburg last week, Dortmund have notched 10 goals in just their previous three domestic showdowns across all competitions.It should also be highlighted, BVB stormed their way to a sensational 4-0 win when they welcomed Villarreal to rural Germany for a Champions League group stage battle back in November 2025.While Villarreal might have received a string of public praise last season as they secured a bronze medal finish among Spain’s elite, the Yellow Submarine have drastically failed to find a similar level this time around.Last seen over the weekend suffering a late collapse on home soil as they slumped to a 3-2 loss against La Liga newcomers Deportivo A Coruna, Inigo Perez finds some increasing pressure on his shoulders.In fact, Villarreal have failed to win any of their opening four domestic showdowns and have put just two points on the board.Despite getting their famous Champions League adventure underway in midweek, Perez’s downbeat squad should be bracing themselves for a stern examination on foreign soil.Likewise, Tuesday’s guests have remarkably failed to claim a single clean sheet from their previous 18 straight appearances.Betting Tip: Borussia Dortmund win & Both teams to score @ 2/1 1xBetOur Tuesday Champions League Accumulator:Real Madrid vs Inter Milan – Both teams to scorePorto vs Manchester
