Johan Mjallby hopes Celtic's Champions League progress will encourage Gary Hooper and Victory Wanyama to stay Mjallby appreciates why Hooper is attracting admirers, but hopes Celtic can fend off the suitors throughout January. "I think Gary's got 18 months left on his contract and we're delighted and we want to keep him," Mjallby said. I think there are discussions now with Gary, his agent and the club. Fingers crossed from my point of view something's going to happen. He's shown that he can do it at the highest level, so I can understand where the interest is coming from. It's down to Gary and what his targets are and what he's looking for. He's just enjoying playing football just now. He's in a good place. That's something that's always going to be important for you as a footballer. The grass is not always greener on the other side. Mjallby believes Hooper would deserve an England call-up in 2013. The assistant boss said: "I certainly hope he gets a chance and if he keeps playing well for us, why not?" Celtic could play Juventus in the next round, with Paris St Germain, Schalke, Malaga, Borussia Dortmund, Bayern Munich and Manchester United all possible opponents. Malaga advanced from the play-offs, but Mjallby expects Celtic to be underdogs in the next round whatever the draw, despite claiming four points in two matches against tournament favourites Barcelona. "We know whoever we come across in the last 16 we're not going to be favourites, so we need to keep the squad together, we need to keep all the good players here and obviously try to do well in the last 16," Mjallby said. The only team who are maybe not doing great in their domestic league right now is Schalke, but they're still a very, very good side, so it doesn't really matter. They sacked the manager but there's still a long way to go (until the matches) and they'll still have time to sort that out. I can see the argument that some supporters want the glamour tie and Man U, but you have to remember Man U are leading the Premiership and doing really, really well at the moment. Mjallby revealed the Celtic squad and support staff will watch the draw together and are relishing the chance to test themselves against Europe's best once again. The Swede, who on behalf of Celtic supporters presented a cheque for £17,809 to Yorkhill Children's Foundation, added: "We don't fear anyone because we've taken a lot of confidence from the performances in the Champions League so far. The players know now they can do something. The first target was to go through from the group stage and now we're in the last 16. It's great, especially when you don't have the Old Firm games this season in the league. It's great for us to be in the last 16 and really have something special to look forward to.
