CELTIC and Rangers have done some good business during this summer's transfer market by picking up players on free transfers.  

The Bhoys landed sought-after striker Moussa Dembele at the expiry of his Fulham contract, while their rivals have picked up eight new players without spending a penny. 

Euro 2016 has provided an opportunity for players who have walked out of or been ditched by their clubs to put themselves on show, and the following eleven free agents suggest that value can be found in the post-tournament market after all. 

Goalkeeper: Michael McGovern (Northern Ireland) 

McGovern is no stranger to followers of Scottish football after spells at Ross County, Falkirk and Hamilton Accies.

He left New Douglas Park at the expiry of his contract this summer and reportedly has clubs queueing up for his signature after an astonishing man of the match performance in the 1-0 defeat to world champions Germany. Glasgow Times: Michael McGovern of Northern Ireland saves from Mario Gomez in the Parc des Princes last night.

Right-back: Aaron Hughes (Northern Ireland) 

The 36-year-old was another member of Michael O'Neill's squad to impress in France, despite his advancing years.

Hughes put himself firmly in the shop window this summer after being released by Melbourne City in July and could prove to be an astute signing thanks to his wealth of experience in England and on the international stage. Glasgow Times: Aaron Hughes recently won his 100th cap

Centre-back: Arlind Ajeti (Albania) 

The 22-year-old defender was called into Gianni De Biasi's side after captain Lorik Cana was sent off in their opening game, and responded with impressive showings against Switzerland and Romania. 

Ajeti has youth on his side as well as top-level experience, having represented Frosinone in Serie A last season.Glasgow Times:

Centre-back: Jan Durica (Slovakia) 

Durica has been a mainstay of his national team for 11 years now and played every minute for Slovakia at the Euros before their last 16 humbling by Germany.

He's unattached after his contract at Lokomotiv Moscow expired and has starred in the Champions League and Europa League as well as winning the Russian Cup last year. Glasgow Times: Wales' Gareth Bale (right) and Slovakia's Jan Durica battle for the ball during the UEFA Euro 2016, Group B match at the Stade de Bordeaux, Bordeaux.

Centre-back: Artem Fedetskyi (Ukraine) 

The versatile Fedetskyi is naturally a right-back, but has performed a range of roles across defence and midfield during his career. The 31-year-old played every minute of Ukraine's dismal Euros campaign, but is without a club after leaving Dnipro over the summer.

Although his entire club career has been spent in his home country, Fedetsky has clocked up 51 appearances in the European club competitions, underlining his ability to play at the top level. Glasgow Times:

Left-back: Ismail Koybasi (Turkey) 

The 26-year-old left Besiktas over the summer despite making 35 appearances for the Istanbul giants last season.

He only played once for Turkey in Group C, but that happened to be during their sole win against the Czech Republic. Koybasi racked up 170 appearances for Besiktas and was a key part of their title-winning team in 2015/16. Glasgow Times:

Midfielder: Migjen Basha (Albania) 

The 29-year-old defensive midfielder starred in his country's historic 1-0 win over Romania, which secured them third place in Group A. He has spent the vast majority of his career in Italy's Serie B,  but spent the second half of last season on loan at Como in the Italian third tier.

Basha does have pedigree though, having made 51 Serie A appearances for clubs such as Torino and Atalanta as well as racking up 19 caps for his country. Glasgow Times:

Midfielder: Tomas Rosicky (Czech Republic) 

The classy Czech playmaker is well known on these shores for his spell at Arsenal, but he left the Gunners in June at the end of a campaign ruined by injury problems.

The 35-year-old captained his country in France, providing an assist in the dramatic 2-2 draw with Croatia, and made 248 appearances for Arsenal while in London. Never mind his age - Rosicky's class is permanent. Glasgow Times: Tomas Rosicky is out for the rest of the tournament. Picture: Julian Finney/Getty Images

Winger/Striker: Hal Robson-Kanu (Wales) 

The Welshman became an unexpected hero after his two goals during his country's incredible run to the semi-finals, which included a spectacular Cruyff-turn and finish against Belgium.

The 27-year-old isn't exactly a prolific goalscorer (he notched five in 35 appearances for Reading last season), but that hasn't stopped him from being linked with Premier League champions Leicester City among others. Capable of playing out wide or through the middle, Robson-Kanu can be picked up for nothing while seemingly in the peak of his career. Glasgow Times: GOAL: Hal Robson Kanu, left Belgium's Thomas Meunier and Marouane Fellaini for dead to score Wales' second goal i the quarter-final

Winger/ Striker: Rubin Okotie (Austria)  

A 25-minute appearance off the bench was all Okotie was awarded during Austria's ill-fated Euro 2016 campaign.

The Pakistan-born forward scored eight times for 1860 Munich in the German second tier last season but has also had spells in Austria, Belgium and Denmark. At 29, he still has more to offer and a point to prove after being dumped by the German club.  Glasgow Times:

Striker: Adam Nemec (Slovakia) 

Journeyman striker Nemec was restricted to two substitute appearances for Slovakia this summer as he seeks a new challenge following his release from Dutch side Willem II.

He cuts an imposing figure at 6ft 2in and is a danger in the air, despite failing to score in the Eredivisie last season. The 30-year-old has also had spells with the likes of Union Berlin and New York City FC recently, but has struggled to settle down at a club.  Glasgow Times:
