Arsène Wenger expects all three English sides to advance to the Quarter-Finals of the Champions League, though he warns that progression is far from guaranteed.
Arsenal are in Porto for the first leg of their Round of 16 clash this evening, while Chelsea take on Inter Milan in the San Siro next week.
Manchester United defeated AC Milan 3-2 in the first leg of their Champions League clash last night, and Arsenal manger Wenger believes the English trio will all be in the draw for the next round.
"I expect the three English teams to go through, yes, but I'm not a fool. I know that it will be difficult for all the three teams," he said.
"Maybe Man United have a small advantage over Milan, but in the other two games it will be very tight."
However, the Frenchman has warned English clubs against complacency, pointing out that other teams in Europe are constantly improving.
"It is normal that people become a little bit complacent," he said. "You are so used to going through: if it is not Arsenal it's Chelsea, you don't care because you travel anyway.
"But I mean you are used to having the teams in the latter stages, so you can be demanding. I don't have a problem with that. But, if you look across Europe, the other teams invest as well. More sometimes. So it's not guaranteed that you have success."
