You can't get away from football this week, not that we at FFC are complaining.

Indeed, Liverpool vs. Manchester United filled our schedule yesterday evening and we're now privy to some Champions League football for the next few days, with four Premier League clubs represented in the group stage.

Arsenal are at home to European minnows Ludogorets Razgrad on Monday night and enter the fixture amid a strong run of form, winning their last six outings across all competitions and not losing since that 4-3 defeat to Liverpool on the opening day of the campaign.

But Ludogorets are by no means the pushovers they may seem; they're reigning champions of the Bulgarian top flight, they held FC Basel to an away draw in September and even managed to find the net against PSG - albeit eventually losing 3-1.

Bearing in mind Arsenal's habit of coming unstuck against lesser Champions League opposition - most notably Dinamo Zagreb and Anderlecht in recent campaigns - we've taken a look at THREE danger men the Gunners must watch out for. They've got what it takes to cause an upset at the Emirates Stadium.

JONATHAN CAFU

Brazilian forward Jonathan Cafu is enjoying a fine second season in the Ludogorets first-team after progressing from their second string, boasting seven goals in 15 appearances across all competitions. That includes two strikes in qualifying and one in the Champions League's group stages - a 45th minute net against Basel. He's also averaged 3.5 successful dribbles per match and won the most fouls per match, an impressive 5.5, of any player involved in the Champions League's Group Stages. That makes him vital to the Ludogorets cause, their best chance of scoring at the Emirates being from a set piece.

CLAUDIU KESERU

Romania v Switzerland - EURO 2016 - Group A

We've not seen much of Claudiu Keseru in the Champions League this season, his participation being limited to just two minutes from the bench thus far. But the 29-year-old was the second-top scorer in the Bulgarian top flight last term and has started this season in similar fashion, netting four league strikes already. He's experienced European football before with Steaua Bucuresti and rather interestingly boasts the fastest hat-trick in Europa League history - scoring thrice past Aalborg BK in the space of twelve minutes back in 2014.

MARCELINHO

PFC Ludogorets Razgrad v Liverpool - UEFA Champions League Group Stage Matchday Five Group B

Marcelinho is Ludogorets' resident No.10 and certainly fulfilling the responsibilities of that position, providing an assist against FC Basel and creating four chances in two Champions League outings - the rest of the squad have conjured up just five chances combined. He's vice-captain after Svetoslav Dyakov and is handy for a goal as well, boasting 57 in 197 appearances throughout his six seasons with Ludogorets. None have come in the Champions League but his top flight return is an impressive four-in-eight this term.
