Celtic boss Tony Mowbray is keen to dampen expectations after The Hoops were drawn with Hamburg, Hapoel Tel Aviv and Rapid Vienna in the Europa League group stage. "When I said after the game against Arsenal that none of the teams in the Europa League would be as strong as them, that was a fair comment," said Mowbray.

"We go into it hoping we can do well but we are very respectful of the teams that are in there.

"There are some really good European teams, and the expectations of Roma and Villarreal will also be very high.

"They have Champions League pedigree in recent years.

"I also saw Hamburg do very well against Manchester City last season, and they have some talented players.

"They are a big club with a lot of money spent on their footballers, so it's a great challenge for us.

"We are looking to be competitive, but I am not going to put an unnecessary burden on the players."
