(CNN) -- Arsenal manager Arsene Wenger had admitted it is "great" to have Theo Walcott back in contention for Sunday's FA Cup fifth-round clash against Championship side Burnley -- but has warned against expecting too much too soon from the England winger.
Arsenal winger Walcott has been out of action since injuring his shoulder last November.
Walcott, who turns 20 later this month, has been out since injuring his shoulder in November.
The problem required surgery, but the teenager has recovered well and is in line to make his first-team return at the Emirates Stadium.
However, Wenger feels Walcott -- who netted a hat-trick for England in their World Cup qualifying win over Croatia back in September -- must be given time to get used to the hustle and bustle of competitive first-team football once again.
"It is very important to see how he will respond with his shoulder and I think he looks to be nearly there. To have him back is great and he can be very good for us," said the Arsenal manager.
"However, the difference between training and competition is different. Theo is very fit but after that you have to get used to tackles and go into the challenges. You have to use your arms and shoulders to resist."
Croatia forward Eduardo is also in contention for Arsenal having recovered from the hamstring injury he collected on his goalscoring return from a broken leg in the fourth round 4-0 victory over Cardiff.
Meanwhile, Chelsea full-back Paulo Ferreira has been ruled out for the rest of the season with an anterior cruciate knee ligament injury.
The Portuguese is the third Chelsea player to suffer the knee problem this season, with Joe Cole and Michael Essien also affected by it.
Ferreira has only been on the fringes of the Chelsea first team this season, starting just one Premier League game and appearing as a substitute in a further six.
