CHRIS Coleman has promised to solve the set-piece problem which has blighted Wales' Euro 2016 build-up.

Wales' vulnerability at set-plays was exposed again when Andrij Yarmolenko expertly finished Ruslan Rotan's 28th-minute free-kick to give Ukraine a 1-0 friendly victory at Kiev's Olympic Stadium on Monday night.

Defending set-pieces has become a growing concern for a Wales side, who allowed Northern Ireland defender Craig Cathcart to punish them from a corner in a 1-1 draw in Cardiff last Thursday.

Wales also conceded twice from set-plays in a 2-0 Euro 2016 qualifying defeat to Bosnia-Herzegovina last October.

"First of all, I must look at myself as a manager and a coach and look to adjust something in the preparation," said Coleman.

"I will look at that because if you look at our record in open play in the last 15 games the amount of goals we've conceded is not very much.

"I'm not giving any secrets away, the opposition will look at the stats (of Wales conceding from set-plays).

"It's definitely something we need to go and work on."

Coleman accepts that Euro 2016 group opponents – England, Slovakia and Russia – will target Wales from dead-ball situations in France.

But Wales have limited time on the training ground and only one more game, against Sweden in Stockholm on June 5, before their Euro 2016 campaign starts.

The Ukraine game was Wales' final run-out before Coleman names his 23-man squad for the finals at the end of May.

Coleman has said that he has his finals squad, barring injuries, already in his mind and he did not feel his players were under too much pressure to perform in Kiev.

"This wasn't a game that was going to be do or die," said Coleman.

"It wasn't your last chance and if you don't take it you're not coming.

"I thought they gave everything they had, sometimes you can give too much and lose a bit of quality.

"But I was really pleased with all the efforts and my only criticism is the set-play, the goal we conceded.

"We could have maybe showed a little bit more in the final third.

"Rather than try and make everything perfect, you have to try and shoot from distance, from an angle or cross it more."

Wales have now won only once in their last six games, and that victory came against the whipping boys of Andorra.

The return of Gareth Bale and Aaron Ramsey, who missed both Northern Ireland and Ukraine fixtures, cannot come quick enough and the pair's presence will be crucial to how Wales fare at Euro 2016.

But Coleman declared himself pleased with his team's performance in Kiev, saying: "It's never easy to come here, even at full-strength it would be a tough game.

"We've come to a tough place to play but we were the team that dictated.

"Apart from the goal, Wayne Hennessey has had one shot to save and we were always the team dictating the tempo of the game.

"We know it's a good test for us because when we play Russia and Slovakia in the Euros it will be very similar."
