Roberto Mancini recognises that Shaun Wright-Phillips will be determined to make an impact against his former club when Manchester City visit Queens Park Rangers on Saturday.
Wright-Phillips spent three years at City during his second spell with the club from 2008 to 2011, but struggled to hold on to a regular place in Roberto Mancini's star-studded side.
The 30-year-old winger has shone at Loftus Road since leaving City in August in the hope of getting more first-team opportunities.
Mancini is glad to see Wright-Phillips performing well but is wary of the threat he will present this weekend.
"I am sure Shaun will want to play very well against us, but I am happy because now he plays in every game - and he deserves that because he is a good guy and a good player," said Mancini.
"We need to pay attention to him on Saturday."
City head to London with a five-point lead at the top of the Premier League and after enhancing their UEFA Champions League prospects with a comfortable 3-0 win at Villarreal in midweek.
Mancini, whose side have dropped just two points in the league and scored 36 goals in their 10 games, said: "Now we need to recover very well because we play just 60 hours after Villarreal.
"I need to change some players because it is impossible, but at least there is a break after Saturday.
"We want to continue to play well if it's possible, but we know that every game is hard."
Promoted QPR have made a positive start to life back in the top flight after a 15-year absence, particularly since adding substance with the signings of Wright-Phillips, another former City player in Joey Barton and others.
A fortnight ago, Neil Warnock's men overcame Chelsea at Loftus Road, a result which - albeit against nine men - made rivals take note.
Mancini said: "They are a different team at home, a very strong team at home and we need to play very well if we want to win there.
"We will try to attack but it's not all down to us - there is always another team, and we need to play very well.
"They also have some very good, experienced players and they beat Chelsea in their last home game, so they deserve respect and have made a very good start this season.
"Loftus Road is a tight, compact ground and it will be hard if we are not at our very best."
The game will also bring Mancini up against one of the game's more colourful characters in Rangers boss Neil Warnock for the first time.
Warnock has carved out his strong reputation in the divisions below the top flight but Mancini has respect for his achievements, which include seven promotions.
The Italian said: "All managers in England are characters - they are strong.
"I don't know Warnock very well because I have never met him but I have seen him on TV and he is a good manager."
