Jol was delighted with the manner of victory over Bolton Wanderers.
Jol said: "I feel the league is very important to them and you can focus, of course, on Barcelona, but they are a different team.
"They are playing unbelievable football and I think, of course, they have to focus on the Champions League but they have to focus on the Premier League as well.
"I think they have to look at it game by game and after that you can see what they have achieved.
"There is a lot of games coming up for them but I feel if they want to be in the top four or top three they have to win their league games as well. I think they have enough players to cope with that.
"You can't say we are playing for Europe but I think we have got too many points to be looking at the bottom of the table.
"I think the only thing is to try to create a winning mentality in our team and get as many points as possible."
