Joe Thomson scored his first Celtic goal in a friendly against Sparta Prague.
17-year-old striker Joe Thomson scored the club's second goal in a 3-2 friendly loss to Sparta Prague, enhancing his reputation.
Thomson has already scored this season in the UEFA Youth League, and has two goals in two games for Scotland's under-18 side.
Deila praised the young striker, and also picked out two other prospects who he felt stood out.
He said: "Joe played well, together with Paul McMullan who did a good job and Jamie Lindsay who did very well today.
"It’s nice to see. They have grown a lot in only a week and they have got some confidence from taking part with the first-team and that’s very important."
McMullan is an 18-year-old striker who himself has played six games in the UEFA Youth League this season, and has played for and scored for Scotland at under-19 level.
Lindsay is a 19-year-old defender with an eye for goal, netting twice in the UEFA Youth League, and himself is an under-19 international.
Giving chances to the youngsters is exactly what such a training camp is for, and gives Deila more knowledge about the academy prospects which can help his long-term planning.
While it's unlikely any of the trio will crack the first team this season, Thomson's goal probably gives him the best chance of a run out at some stage, but all three will be delighted to have caught their manager's attention, and seized their opportunity.
