The retired winger has warned the London giants not to be so dismissive of his side as the two sides prepare to go head to head in in their upcoming Champions League quarter-finals clash next month.

The quarter-finals of the 2020/2021 UEFA Champions League may be a few weeks away, but tensions have already started to rise between some of the teams.

And some of the players involved aren't even going to be on the pitch.

Namely, retired Porto icon Paulo Jorge dos Santos Futre, commonly known simple as Futre, has reportedly and rather unfortunately taken offense to Chelsea's apparently "disrespectful" reaction when the Blues found out that they will be facing the Dragons in the quarter-finals.

Chelsea successfully dispatched Spanish outfit Atletico Madrid - a team known for their mean defense - to deservedly book their spot in the final eight, while Porto battled through 180-plus minutes of action against Turin titans Juventus to also rightfully secure a place in the quarter-finals.

So, it's safe to say that both teams have earned the right to celebrate their achievements so far this season, especially in the Champions League. Since Thomas Tuchel took over, Chelsea have gone 14 matches sans defeat, while Porto, although they are a whopping ten points behind Sporting CP in the title race, they've lost just twice in the Primeira Liga and they're back in the UCL quarter-finals for the first time since the 2018/2019 season.

Chelsea do have a good track record against Porto, with five wins from their last eight meetings, but despite offending Futre with their percieved "impudent" celebrations, the Blues obviously won't be going into the first leg at the Estádio do Dragão over-confident. After all, this is a team that beat Juventus 4-4 on aggregate despite most pundits backing the Bianconeri to progress. And their top goal-scorer isn't an out-and-out striker, but rather midfielder Sergio Oliveira, which shows that the Portuguese giants are a threat from many quarters on the pitch.

But to begrudge Tuchel's men the right to celebrate having sent Diego Simeone's hearty team packing is maybe bit much and unfair as one can be certain that Porto's players were likely - and rightfully - also celebrating booking their spot after dumping the Italian powerhouse out of Europe's biggest club competition. And the Dragons also certainly were also relieved they didn't have to deal with reigning holders Bayern Munich, who, as per usual, have been in their traditional ruthless form as they look to successfully defend their crown.

Plus, whoever wins this tie will have to face Liverpool or Real Madrid next. Those are the two teams who won the Champions League prior to Bayern Munich, by the way, and and it will be very interesting to see Futre will have to say if Liverpool or Real Madrid "celebrate" if they're drawn against his former team should they beat Chelsea.

That being said, Porto's players should now have even more incentive to give their all when Chelsea come to town next month - which should make for a very interesting quarter-finals clash for fans and neutrals alike.
